Letter to the pregnancy time line.

post #1 of 43
Thread Starter 
Dear fictitious gestational chart/ time line:

For a long time I have been rather confused by your nature. I've recently learned to except a couple of your crazy 'rules' such as the fact that the first two weeks of my 'pregnancy' I am in fact, not pregnant at all. I realize the reason for this is because 'most' women don't know the date of their ovulation, so I except it. I have also excepted, but am not happy about the fact that we are actually 'pregnant' for 10 months, not the universally known 9.

Let me break down my concerns week by week. We'll start with the first 'trimester'. The first trimester is usually depicted as the first 12 weeks of pregnancy. But do not be fooled. You have only been pregnant for 10 of those weeks, which does not add up to three months. So the first 'trimester' should go up to 14 weeks, not 12. Maybe this explains why my morning sickness never magically disappears at 12 weeks. So why is it that we tack those extra two weeks on to the beginning of the pregnancy? Why not put them at the end, distribute them evenly, or take them out all together? I guess the world may never know.

Now let's go ahead and make matters even more confusing, shall we? Even if we were to hypothetically take away those first two weeks in which we all know we aren't really pregnant, women still gestate for 38 weeks. That puts an additional two weeks on top of the mysteriously inaccurate 9 months of pregnancy. So where do these extra 2 weeks get distributed? Well, that depends on which piece of literature you are reading, which cell phone app you use, or which doctor you talk to. And again, let's not forget the two phantom weeks that also need to be factored in.

Here is a really out there concept, so bare with me. The extra two weeks at the beginning of pregnancy is there for one reason only, which is to calculate an EDD for those women who may not have known when they ovulated. When using this system, we make the assumption that the woman in question had a 28 day cycle and ovulated on day 14. This in itself is absurd since this isn't true in most cases. But putting that fact aside for a moment, why not continue using the 28 day cycle DD calculator, but not add the additional two weeks. For example: woman goes to the doctor. Doctor asks woman for her LMP. Woman states it was on December 1st 2009. Doctor gives her an EDD of September 7th 2010. But here is the kicker.......instead of telling her she is 7 weeks pregnant, he tells her she is 5 weeks pregnant. Now this may be hard for providers to wrap their heads around I guess. I realize all the info online about pregnancy would have to be tweaked a bit. But wouldn't this make for a much easier comprehension all around?

During my last pregnancy, I bought a book to track my progress. The book operated in this way, knocking off those two weeks all together. I loved the book, but it made it confusing for me. Every doctor appointment I had I was told that I was at a different week. If only everyone could get on board with the system this book used. For once the gestational age of the mother and the fetal age would match up. Oh, but that would just be too easy wouldn't it?

On Sunday I will be reaching a truly exciting milestone in my pregnancy. I will have completed my 12th week of 'gestation'. But as you can see by my concerns here, I'm sure you will understand that I will have a hard time celebrating the end of my first 'trimester' as we all know how untrue that is. I won't be expecting my morning sickness or exhaustion to vanish. And I won't be expecting my belly to suddenly become round and pregnant looking. But I will know that for 10 weeks I have been creating and growing a tiny baby. I have hopes that when my children are having children I won't have to explain this silly system to them.

Sincerely,

Just some gestating female

(To you fellow preggos, I woke up at 1am last night and these thoughts circled my head for hours at the face of pregnancy insomnia. Maybe writing it down will assist in someone else getting a full nights sleep )

Very true!! Who are the powers that be who decide to make things confusing in the first place?

I would also add to your letter why we are still using the 40 week gestation (38 week really) as the measurement for a length of a normal pregnancy. This was made standard around 1850 and remains today even though research says it's not accurate!

Urg, I hate the phantom two weeks, too. It's very irritating to me that books don't always tell you which system they are using; the gestational age, or the actual weeks pregnant....I guess you assume to add on the extra two weeks.

Now, there are lots and lots of women who have no idea when their LMP was, and are then given an early u/s. since these things are supposedly so reliable, it would make sense to go by the actual weeks pregnant for these women, but still the medical community tacks on two more weeks. crazy

Well, since I've been sure of my conception dates (within a day or two, obviously), I've always counted 40 weeks from that, and been pretty accurate at predicting my due date. Again, not always perfectly, but very close.

I really think is all part of an evil plot to keep women out of tune with their bodies. Probably goes back to the hatred/persecution of witches and stuff. (Actually serious on that front.)

I think as a part of every high school (or junior high) health class, girls should be taught fertility awareness. They should learn how to read their own body and understand it. Whether they want to some day have kids or not. Much more useful than abstinence education IMHO.

I get frustrated because I use different sources and they all seem to use a different method.

I prefer to think of pregnancy as ten moon cycles long

I think the 9 months comes from it being about 9 months from when you REALIZE you're pregnant (the old fashioned way...hey where's my period?, and start getting the quease) to when you actually have a baby.

And due dates? They aren't worth much no matter how you calculate them. None of us has a pop up turkey timer that goes off on our due date, so it's more of a general guideline for when you "might want to expect to be having a baby."

I do think it's bizarre and confusing to have to count those extra two weeks. I would have been 12w 5d or so from LMP today, but per my US I'm 11w1d, and either way, I don't feel good!!

I think its because its 9 calendar months from your last period (my last period was in December, I am due in September, 9 months later...)

I mean, if we only counted months as 4 week increments as we do in pregnancy... a year is actually 13 months long.

My last period was in late October and I'm due mid August. Do the math on THAT one!

You Oed late :P you don't count! (well the last week of Oct would still be an early Aug due date, but neither of those should really count as a month...)

I had to comment on this one. With my daughter my last period was the middle of June and my baby was born at in Mid April.

(No period for six weeks, checked for pregnancy, did ultrasound, ect. not pregnant. Had a tiny bit of spotting, told to come back next month if no period to figure out what was wrong. Six weeks later, returned. Dr. was sure they just missed the pregnancy last time and I had to be 8-12 weeks pregnant. Nope. 4 weeks gestational age - 6weeks pregnant by the pregnancy time line. They finally made up a LPM that corresponded to my due date as determined by first trimester ultrasound to make my chart less confusing.)

I agree that fertility awareness should be taught. IMO, abstinance should also be taught. We teach young people not to have sex... UNLESS they use birth control. Apparently that makes it more "moral" or something.

Actually I think it prevents unwanted pregnancies and sexually transmitted diseases or something.

Teaching abstinence will not make them follow it.

Thank you! While it did not help me sleep it did remind me of being pregnant with DD and trying to wrap my head around the fuzzy math. Completely insane!
post #16 of 43
I just have to say to the OP, AMEN SISTER!!!

I thought I was the only one throwing my hands up in utter confusion.

I have a period every 2 months, so it's a little odd that the medical community and I are pretending my LMP happened in an entirely different month just to justify the 2 phantom weeks.

ugh
post #17 of 43
Ugh, this post read what was my on my mind today!! Now that I am 7.5 months pregnant, and starting to feel BIG and uncomfortable and counting the days (ha), I can already see the confusion of "but if you're 7.5 months, then why is your baby due in April?!" starting to mount... why on earth IS it that people think pregnancy is 9 months?! The whole thing seems dishonest and anti-woman to me. I read that in France a regular pregnancy is considered 41 or 42 weeks, not 40.
I try to laugh but it also feels kind of frightening and unsupported to have the disinformation that pregnancy is only 9 months... like everyone is going to start going, "WELL?!?!" a month before my due date.
Grumble... anyway, great post!
post #18 of 43
Oh, and I remember well being about 10 weeks pregnant and thinking "it'll all be better after the 1st trimester/ 12 weeks." Then my midwife said, "actually... it's really more like 14 or 15 weeks that you'll feel better." WHAT?!
post #19 of 43
I have just given up entirely on the whole "months" thing. I have a 35 day cycle and ovulate on day 21. When they (doctors, ER, etc.) ask about LMP, I tell them when it was and then amend to tell them that according to u/s (and common sense) I'm due a week after that. People will ask how far along I am and I tell them in weeks, according to traditional 40 weeks, basically counting edd as week 40 and going backwards from that. They'll say "oh, so you're in your 5th month" and I just kind of say "pfft I don't know. I'm due June 30, so whatever that makes it." In the grand scheme of things, I really don't care. Most of the time I have to look on my siggy at another message board to tell me how far along I am. I just know it is not June yet.

OP here. Glad this thread has gotten so many responses. I knew I wasn't alone

Just a few things. I totally agree that in the whole picture, these 'time lines' don't really matter. EDD don't really matter either, and baby will come when baby is ready. It only irks me because of so many women who become confused by it, or even worse just go along with it and it ends up a mess. EDD being changed at every visit. Inductions scheduled when she still has one or two weeks to go. It really is a recipe for disaster. I agree with umsami that it is probably a secret plot to keep us confused and out of tune. A ploy to make us put our trust in our provider because we have no idea what is going on.

I totally agree with the school education discussion going on here as well. I never understood why schools NEVER teach you about ovulation or conception. I remember my school telling me that no matter when you had sex you can get pregnant. I know they say that because many teens don't know their cycle yet, but come on, that's just a flat out lie. They never taught us how a cycle worked, or what it was. They just said, you'll get your period, and don't have sex.... I hope the system has changed some but I doubt it.
