<p>Hi everyone!  I'm new here -- Sorry haven't introduced myself in the roll call.1</p>
<p>I just got my BFP about a week ago, so I'm just sort of lurking on the fringes with my fingers crossed and reading as much as I can!</p>
<p> </p>
<p>So far my biggest confusion:</p>
<p>I ovulated on/about  Nov 22 - so that would make me about 3 weeks pregnant, gestation.   Don't those 2 odd weeks that most doctors tack on there by counting from your LMP make a big difference from a development point of view? </p>
<p>For purposes of discussion with other women, they will ask, "So how far along are you?"  Do you always just use the standard that most people who see conventional doctors are used to... even though it's not technically correct?  I'm very nervous about being pregnant for the first time, and trying to decide when to tell our family is odd.  When are we out of the woods, as far as danger of miscarriage?</p>
<p> </p>
<p>Thanks for all your input!</p>

<p>Yeah, it's confusing! Refer to how far along you are by counting those two weeks, because that's what everyone will go on developmentally. With my first, the ultrasound technician said I was measuring 12 weeks at my first appt, which had me freaked out that I was having a big baby because I knew for a fact I was only 10 weeks. Which I was, but I wasn't counting the two missing weeks. </p>

<p>You are right...you are 3 weeks gestation, but most American stuff goes by adding 2 weeks to that to assume a 2 week period before ovulation.  The nice thing about knowing your ovulation date is that if you are not a 28 day cycle person who ovulates around day 14, you can get a much more accurate idea of when you are due.  You can go to some online calculators to find your due date.  Google "due date by ovulation" and you will get the option to use LMP or ovulation date.</p>
<p> </p>
<p>I've been looking up miscarriage stuff too.  Paranoid first time mom!  Anyway, most stuff says a 15-20% chance in the first 12 weeks.  However, on closer inspection, it seems that the majority happen very early and are from chromosomal abnormalities.  Beyond that, the reasons for miscarriage were low progesterone, ectopic pregnancy, chemical pregnancy, and cervical incompetence.  There were others too, but these were the most frequently mentioned.  I found a nice handy dandy chart that was very reassuring.  Basically that 15-20% was broken down like this:  75% of that amount was in the first before your missed period, 10% for weeks 3-6, and weeks 6-12 was 5% and after 12 weeks was 3%.  It said the number is even lower from 6 weeks on if you have seen the heartbeat...I would assume the same (or better) for after hearing the heartbeat (if no ultrasound) anytime after week 9/10.  I finally decided to stop researching because I am doing everything I can to keep this little one safe.  I hope he/she knows how very much I want him/her.  If there is a chromosomal abnormality that happened by chance and the little one would never have a chance of living a normal life, then I know I loved it and cared for it the best I could while it was in me.  Other than that, my HCG numbers suggest it's unlikely to be a chemical or ectopic pregnancy, I have no reason to suspect a cervix issue, and I am on prescription progesterone for an already known issue.  I've been stressing too much and not enjoying this baby enough.  Now that I have relaxed a little, it's so much more fun!  I rub my belly and talk to it and tell it goodnight every night and let it know how much I want it to be happy and healthy.  I'm hoping good thoughts will do something. </p>
<p> </p>
<p>Anyway, just thought I'd share my experience and information with you.  It's soooo hard not to worry when you want something so bad, but since it's out of my control, I'm trying really, really hard to try not to stress and focus on it so much that I take away from the joy of it all.  We're pregnant!!!!!  <span><img alt="joy.gif" src="http://files.mothering.com/images/smilies/joy.gif"></span></p>

<p>Yes, count those first two weeks.  They are factored in.  I was so confused the first time too, I wanted to read things for "one week pregnant" not realizing that I was actually 3 weeks gestation and that information was accurate for the stage I was in.</p>
<p> </p>
<p>Also, lets say down the line you are 6 weeks 4 days, you are technically in your 7th week so you can read development for week 7.  I always thought that was interesting too.</p>
<p> </p>
<p>Bree - that breakdown is very reassuring!  Thanks for posting that!</p>

<p>THanks everyone!  This helps a little.</p>
<p> </p>
<p>So do I assume that on this forum, you are all mostly referring to how far along you are by counting from you LMP?</p>

<p>emjg - for people who chart or otherwise know when they ovulate, I would say they go with O date +2 weeks. Which is, in theory, what calculating from LMP is, just more accurate. But, yes, I would say that most people tack on the extra 2 weeks.</p>

<p>I consider those 2 weeks as "freebies."   As in "look- I just got my bfp and I'm already a month along!  Yay!  Only 8 more to go!"  :)</p>

<p>I know you guys have already explained this but I have a few more questions about dating. I have longer cycles and I ovulate later. My LMP was on 11/10 but according to my FF chart I O'd on 11/29. So by my LMP I would be 5 weeks 2 days right? Well I feel like technically I am a week earlier which would put me at 4 weeks 2 days. Am I right or just confused? lol When I talked to my midwife group over the phone I told them I thought I ovulated later and they said they would still go by my LMP. I am just worried the first time we try to hear the heartbeat or get an ultrasound I will be earlier in my pregnancy than they think and we wont see or here anything. I just don't want to deal with that stress when it could be avoided.</p>
<p>Also if I am 4 weeks 2 days does that mean I have completed 4 weeks and I am entering my 5th week? Thanks for the explanations!</p>

<p>Personally I would say that if you feel confident about your ovulation date, I'd go by that.  There are online calculators that can tell you your due date based on that instead of your LMP.  I think if it's only a few days off, then it doesn't matter much, but a week can make a big difference.  Maybe when you see your doc you can really explain it...or if you are super confident in your ovulation day, just tell them your LMP was later than it was...I don't know. :)</p>
<p> </p>
<p>Good question about the four week thing...I'm not totally sure, but I think if you are 4 weeks and 2 days, you have NOT completed your 4th week yet, but I'm really not sure at all.  Today is 7 weeks, 0 days for me.  I'm not sure if I'm in my 7th week or 8th week.  Good question.</p>

<p>I already told them my actual LMP when I spoke with them on the phone to set up my appointment. I will just explain to them that I ovulated later and if they want to go by my LMP I guess we will find out when we try to hear the heartbeat or do an ultrasound how far along I really am.</p>
<p> </p>
<p>I am 33 days today so I am assuming I am entering my 5th week. I could be wrong but 28 days would be a full 4 weeks right? So I am 4 weeks and 5 days. I just don't understand why this is so confusing to me! lol I just want to know how old this tiny bean is :) That way I know when I can hopefully get my first ultrasound!</p>

<p>It is the standard for OB's and other medical professionals to go by LMP for dating purposes, even if you are 100% sure of when you O'd and that date is different than CD 14.  That's a major drawback of the medical profession, IMO.  What will happen is that you will be given an EDD based on your LMP that will be off by the number of days between CD 14 and the CD that you O'd.  In your case, karalynnskies, that would be a difference of 5 days. </p>
<p> </p>
<p>As long as YOU know that, you shouldn't worry about measurements being off when you have an u/s.  Ultimately, YOU have control of how your prenatal care is handled and if your OB is pressuring you to have procedures done based on a smaller than expected fetal measurement, you can decline, if you want to, knowing that the date is just off.  This includes pressure to be induced because you are "overdue" when maybe your baby just isn't done developing fully yet. </p>
<p> </p>
<p>As far as counting the weeks is concerned, when you are 4w2d, you have completed four full weeks and are two days into the fifth week, etc.  The gestational age of the fetus is only 2w2d though. </p>
<p> </p>
<p>For most practical purposes, you will never use the gestational age of the fetus when discussing how far along you are.  The only time that gestational age would be important is when looking at clinical journals that show pictures and describe the development of the fetus at various points in time based on actual development, not length of pregnancy.</p>

<p>Thank you so much! That did clear everything up for me. When I have my first meeting with the midwife group I am going with I will make sure to tell them again about my late ovulation. Since they work through a hospital I am going to bring up induction and find out what their policies are. If I don't agree with them then I will be finding someone else to handle my prenatal care. And seriously thank you, now I feel like I actually understand how all this dating stuff works! I appreciate it <span><img alt="smile.gif" src="http://files.mothering.com/images/smilies/smile.gif"></span></p>

<p>DDCC-- My midwife group did the same thing, where I told them I knew when I ovulated and they insisted on using my LMP date, so I said "You might as well put it down as [14 days before my O date] even though that wasn't when it was", and that's what they did. Eyeroll. But I'd rather have done that than have to deal with telling every single practitioner the date is wrong and having them not believe me. If they ask me for what I know is garbagey information, I don't feel too bad about giving them information that's technically wrong but actually more useful than what they actually asked for.</p>
<p> </p>
<p>The whole dating thing weirds me too, particularly how you are considered 2 weeks pregnant when you have just ovulated, so in a sense ALL women are pregnant for 2 weeks at the beginning of their cycles! Super creepy. I told my friend who has irregular cycles about that, and she said she must be 7 months pregnant [she's not pregnant at all].</p>
