I was going through my medical records today....have only seen midwife 2 times and have had 2 US. Pretty much a UP pregnancy...in a way. So i was checking out my US print outs and it says per the US....EDD is a week sooner than going by LMP dates...this was on both US print outs. Just got me thinking...which due dates are other mama's going from. The US due date or your LMP due date? I know that baby will come when ready....but i was thinking... hey baby may be earlier than what i thought. Just something to keep my mind busy while i'm waiting...so what are yall going by?

I'm going by LMP because it makes 42 weeks a few days later than by ovulation. Thus, less fuss and worry for my midwife and me. I haven't had an u/s, so I don't have that date to go by.

Neither - my cycles are short, and I know the date I conceived so in my head i'm going by that. My MW is going by LMP though.

Just a modifiedartist.gif trying to find some peace and regain my balance.

Going by O date. MW is using LMP plus a few days... I begged her to make my official due date a few days later because I thought I'd be close to 42 weeks and here that risks you out of MW attended homebirth.

Apparently I am going by the ultrasound as my LMP doesn't fit with it. I usually ovulate later than most so this makes sense.

I'm going by LMP as I prefer to have my weeks change on Saturday - My OB is going by O date however.

Neither. I'm going by O date also. On a side note, it's a good thing my 1st mw went by this date too w/ DD because if we went by LMP, she would've been considered 3 weeks "overdue" instead of 1 week. (I had really wacky cycles.)

My situation is a little confusing. According to early u/s, I am due September 22. But if you go by when I KNOW I conceived (and yes, it can be off by a few days), it's about 2 weeks before that. I originally thought I was pg (got + tests) and then got a tiny bit of spotting, which my m/w thinks was a chemical pregnancy. But it wasn't a full period. We DTD a few weeks later and then I got more + tests, and got my hcg levels checked. The levels were pretty low for where I thought I should be, thus the early u/s. SO, after all that, I'm going by the u/s. If I went by LMP, I would be due right around now, and there's no way I'm full term. This is the weirdness of an unplanned pregnancy, I suppose.

I'm going by my ovulation date, since I was charting. LMP wouldn't be accurate for me (especially since I o'd on like day 22), and I haven't had an u/s.

If I had to pick between u/s and LMP and was planning to birth in a hospital setting, I would choose whichever one is later.

This was a clomid cycle, so I had an u/s on day 14 which determined that I hadn't ovulated yet and was unlikely to . I'm pretty sure I Oed in the next 2 days, so I'm going by that, which happens to match up with my early ultrasound for dating (why we needed to date a clomid cycle, I'm not sure). So I'm saying I'm due 9-23 wheras my LMP says 9-21. I hope we don't get to the point where those two days make that big of a difference, but if we do, I'm going to use them for leverage! I still have my weeks turn over on Sunday (which goes with the 21st edd, though), because somehow that's what got stuck in my head.

With DS2, I knew that I'd ovuluated about 5 days late, so I said all along that I was due on 7-15, not 7-10 like my LMP said. Sure enough, he was born on 7-14. I'm hoping this LO is that close to his due date, too!!

With a date of conception at 12-25 the EDD would be 9-16 according to some random calculator I found online.

Charlotte - you and I are a day apart! I'm due by LMP on 9/20, O date of 9/22. Those two days are important for me since my doc schedules inductions at 41 weeks. I hope I won't need those two days...but I'm glad to have them just in case.

I will say though that almost every u/s we've had, she's measured ahead. Six weeks put her at 9/19, seven weeks was 9/22, and nine weeks was 9/18.

MW is going by LMP, which puts my DD at 9-5. I know that I conceived on the Winter Solstice (only day that DH and I DTD for that week), which makes my DD 9-12. If I go late, I'll show my MW my charts and insist on the 9-12 DD so I don't get pushed into induction.

My U/S date is August 30th. My LMP is Sept 3rd and my conception date is Sept 5th. My midwife said "pick date" so I chose Sept 7th.

Ultrasound dates but they were surprisingly spot on with my date of ovulation. I didn't have a period so we can't go based on LMP! Ultrasound date gave me September 30th. Date of ovulation gives me an EDD of October 1st. Close enough.

You could have conceived up to (I think?) five days later than that, actually, since the sperm can hang around and wait for the egg.

Did you tell her your O date? I'm surprised she's going by LMP if you know the O date... I didn't even tell her when my LMP was, and she just calculated the due date off of O. Of course, she's not pushy about going "overdue" so it doesn't matter too much... I'm just curious.

My cycles were a bit weird, but the midwife is going by the LMP as it gives me a 8 day later due date (Sept. 7) then my ultrasound, which was August 31st. I went over 2 weeks and 10 days with my others, so they take as late as we can get!! However, I have to say I was seriously relieved when I hit 37 weeks (by the US date) that I could have a home birth.

Both, as they are the same. September 14th either way. As far as I can remember I either O'd the day or the day after we came back from our little mini vacation in December and either way then from the O day i'd still come out with the same date. lol. So, September 14th, September 14th, or maybe September 15th.

And no one has said anything about measuring the height of the fundus (even tho it's totally inaccurate). If I went by that i'd be measuring 2 weeks ahead right now... so obviously that's not reliable at all.

We're going by early u/s. I'm not regular at all and don't pay any attention to my cycles anymore. Early u/s has been correct the other 2 times as well so I'm confident in the edd.

7th Heaven here we come! Due date early May

My fundal height has been measuring pretty much on schedule with the u/s date so I'm taking that to mean it's fairly accurate.

Same here.
Originally when I found out I was pregnant I was all excited and looked at my due date based on lmp which would make me due Aug 28. At my first midwife appt we calculated my due date based on ovulation (which I knew from using an OPK) and that gave us a date of Sept 3.
But I had started taking weekly pictures based on lmp date and got that stuck in my head. So now I am trying to readjust to being a week "behind" and it's been hard especially since there is such a big difference in my mind between 37 and 38 weeks .

I went by my conception date. We did the Shuttles method so I know the exact day I concieved. Otherwise, I always go by the period method. I do NOT trust ultraounds at all-for instance, I had one the day before my first was born and it estimated his weight at 7lbs and 19 inches long. The next day he was born weighing 8lbs 6oz and 21 inches long. REAL ACCURATE THERE. lol

Its said all my babies were small and then they come out normal size so I just have a hard time trusting it. I'd rather not mess with my due date.

I'm going by my u/s date because it is the latest one. If I went by LMP I would be due Aug. 26. I know the conception date which would put me at Sept. 11. My u/s said Sept. 13 though. I figure the later the better.
