Since I was not charting, I don't know what day I ovulated. So going by first day of menstruation I'm at 8 weeks. But it looks like those who've had u/s are going by the actual gestation. Why am I concerned? Well, just the anxious countdown until 1st trimester is over...

I use LMP, but I'm not all that worried about dates ~ baby comes when baby is ready.

I use LMP even though I know when I ovulated & concieved.. its all within a few days for me anyways..my cycles were pretty consistent and text book. I always go with the date that is later since I tend to go later.

With my DS I went by LMP, and that was a huge mistake for me. My cycles are usually long, while most people O on CD 14, I usually O on day 21ish. So my "due date" with DS was August 14. It should have been August 25th, going by conception/ovulation date. It was awful waiting those extra almost 2 weeks, and I was induced since he was a large baby (9 lbs 3 oz) and I was 12 days past due. Everything turned out fine in the end, I was still able to have a drug free vaginal birth, but it was a long (17 hour) labor, with contx that were one on top of the other the entire time due to pitocin induction. Luckily I had a very supportive midwife who stopped the pit once I got to 6 cm's and I was able to labor naturally for the second half of my labor.<br><br>
This baby, I know my conception date, and I started taking PG tests at 10 DPO, first one was negative. At 12 DPO I got a faint positibe. At 14 DPO I got a very solid positive. If I was going by my LMP, I would be 12 weeks. But since I'm going by 2 weeks before conception date, I am 10 weeks 5 days. That extra week and two days are really important for me, because I do NOT want to be induced again. If you are uncertain about your date and don't usually have regular cycles, you could get an early US for dates.

I was surprised that with DS1 the LMP was accurate - because he was past the due date and had all the wrinkly skin to prove it!<br><br>
Like I said, I'm just counting down days for this nausea and exhaustion to stop. <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile"> If I had money for a u/s at this point, that would be fun...but we're self-pay for everything.

This is very interesting - how long are your cycles then, usually? My 3 have been induced for postdates, and I'd like to have a naturally-induced, normal labour this time. I'm going with a midwife this time, which will increase my chances already, but now I'm curious about how you calculated your numbers? How do you know the day you ovulate? Please share!

I read the book "taking charge of your fertility" and it tells you signs of ovulation such as certain cervical fluid, temperature, cervical position, etc. Since reading that I am very aware of when I ovulate, mostly based on cervical fluid and my emotions, etc. My cycles were normally 5-6 weeks long, but since having DS they were even longer, I just got my first period in October, and he was still nursing so they were like 6-8 weeks. Typically you get your period 2 weeks after ovulation, so that is another way you can calculate by going backwards.

I was loosely recording my info on fertility friend.... I only charted AF and occasional CM, usually when I felt ovulation was at hand. I was gearing up to have a 28ish day cycle, I think.<br><br>
Looking at my chart I'm really not sure exactly when I ovulated. I had a few days of fertile mucous, so I guess it depends largely on when the egg was released. lol If I go by the very last day of fertile mucous then I first tested positive at 8dpo. If I go by a roundabout estimate I got my first positive at 10dpo which seems more likely.<br><br>
I'm going off of February 14th as my conception day. Though I'm sure that could be a few days off for sure. Anyway... it's hard for me to figure because I used to have long cycles and I always go way over (past 42 weeks with my 4th) and so really it's all a ball park for me anyway. I am pretty sure my midwife is willing to work with me and my dates rather than against me. So that's a plus. I'm 10 wks 4 days by my calculations.

I ovulate on day 16, which I know from charting my temps and checking my cervical fluid.<br><br>
Unfortunately, my husband convinced me to stop charting because he thought it was stressing me out while we were TTCing. So it took some funky math plus my ovulation pattern from other months plus the implantation bleeding dates to get an EDD.<br><br>
But it doesn't really matter anyway, because my midwives are pretty laid back about due dates, and they depend a lot more on the dating they do with fundal height, etc. So yay for that. If I was going to a run of the mill OB I'd probably get a dating ultrasound so that I could avoid induction.

Personally, I'm going with my ovulation date, since I was charting...and that's the basis for my due date of Nov. 4. But when I went to the CNM for my first appnt., they just asked about my LMP and the dating U/S...and came up with a due date of Nov. 6. I'm going to let them keep that date, just in case I really do end up having to stick with them and deliver at the hospital. That way, if I happen to go past the due date, it will give me that extra two days of not having everybody panic. <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/winky.gif" style="border:0px solid;" title="Wink">

I'm going by the day I conceived (only day we had sex!), so I am 8 weeks, 5 days post conception.<br><br>
But technically I'm 10 weeks, 5 days pregnant.<br><br>
Make sense? Didn't think so. No one, and I mean no one (doctors, other nurses, MWs, etc) can explain to me why the heck we consider women pregnant a full 2 weeks before they even ovulate!<br><br>
PS-Demeter! We're conception buddies! We both seem to have made a Valentines baby. <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/thumb.gif" style="border:0px solid;" title="thumbs up">

Because most women don't know when they ovulate, and don't remember when they had sex, but many do keep track of when they expect their periods.<br><br>
With DS, I did my best to subvert the traditional dating since I knew exactly when I had ovulated, but it was a bit of a pain when trying to translate between how pregnant I considered myself and how pregnant the world considered me. This time around, I'm going with LMP by default, because I have to class myself with the "most" women of my first paragraph <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/redface.gif" style="border:0px solid;" title="Embarrassment">.

No, I get that most women don't know. I understand the need to apply some sort of uniformity and consistancy to pregnancy dating, and I understand the logic behind basing it on the "average" woman.<br><br>
But then why not consider her pregnant 2 weeks <i>after</i> her LMP? Why say she's "10 weeks pregnant" when you, she, and the ultrasounds all say she's been pregnant for 8 weeks? When you know the sperm didn't meet the egg (which wasn't even released yet) for another 2 weeks (roughly) after the LMP.

I go by date of conception because there's only one possible day (I suppose it technically could have happened a few days later, but it's still going to be more accurate than LMP, which places my EDD several days earlier, which isn't possible), and it corresponds with my ovulation signals (not charting, just the ones that are easy to notice. Like actually having a sex drive).<br><br>
I re-figure my "LMP" for healthcare providers based on that unless they seem willing to accept that the known conception date is more accurate.

I agree it is confusing and annoying. I think the way it was explained to me was that your body is creating the environment for the embryo at the beginning of your period. I just figure that the baby grows so fast in those early days/weeks that it doesn't really matter. Like they do an extra 2 weeks worth of growth in a day's time, compared with how fast they grow in the second and third trimester.

My cycle is normally 35 days. I know when I conceived. But, if I let my doc know that little secret then my due date would be bumped a week later. I don't mind that, but I had a cousin that had a miscarraige three days before they would revive the little one. They just let Own die in her arms. Had she miscarried three days later they would have tried to save him. So, I don't want them to move my date any later in case those three days matter to me.

by LMP I am due Nov. 6, but I think it's more like Nov. 11 (my birthday!) based on fertility signs/testing. I think it would be strange to get a BFN (well, maybe the faaaaaintest BFP, but I have a wild imagination and I didn't even believe myself) on CD 29 if I actually ovulated on CD 14. My midwife doesn't really care, she is extremely low intervention anyways (encouraging me to skip ultrasounds, etc). But I am keeping the Nov. 6 for now, so that I can say I am out of the first trimester on Saturday!

I go by ovulation/conception. I had positive OPKs at cd17, so FF says ovulation was CD18. Of course, as others said, I'm working with a MW so we're not going to freak too much over dates. It's nice to know when things really happened, though!
