Going by LMP or by "O" date?
Is everyone going by LMP as far as their EDD is concerned? I know when I "O", but my doctor still wants to go by a different due date.
The thing is, is that I found a very, very small blood clot when I wiped so I went in today for an ultrasound. The baby looked great, they can't find the reason why. Going by my ovulation date I am 11w5d. Now if I go by my LMP I'd be 12w0d today. Well, the baby measured a week ahead which would be 12w5d if I was 11w5d today, and my EDD has been 9/22. Well, she wants to go by a 9/20 EDD, but she put me at 12w2d now??? I don't understand? I didn't get to calculate it until I got back to work, but I didn't even ovulate then? I'd hate to call my OB/GYN just to ask this question. She said I can go by the 9/22 EDD if I want, but she's going by 9/20. If my EDD is 9/20 that would be my LMP which would make me 12w0d. I have no idea where she got the 12w2d from? Any ideas? What do you girls think? HELP... I'm so confused now!!! Thanks!

Its only really 2 days so I wouldnt worry about it to much. Those U/S's can be off a few days, which is obvious in your case. I would however go by your doctors EDD so that your both on the same page for if your late, when your late and things like that.

I too had all these problems with my EDD regarding my LMP, my "O" date, and the size the baby was measuring. Since it is only a matter of 2 days for you (the same as it was for me), I just use the EDD the doctor gave me. It really is only a window anyway, not an exact science.

Re: Going by LMP or by "O" date?
Thanks for the replies!
My concern really is, is that if I go by the EDD that she wants me too, than it's only a matter of 2 days, but if I go by how far along she says I am which was 12w2d, than it's a matter of 4 days?
I forgot to mention it, but the reason I'm so concerned is that she's having me come in 3 weeks from today to do the AFP test. Which if I go by her EDD I would be exactly 15w0d, but if I go by my ovulation date, I will only be 14w5d. So I don't mind going by her EDD, but when it comes to the AFP test it's suppose to be done between 15-18 weeks, right? So if technically I'm only 14w5d, won't the results not be accurate like they need to be? Would that much of a difference in days make that much of a difference in the results? I think 2-4 days can make a difference and if I'm technically not 15wks yet, it might come out wrong. Maybe I'm just confusing myself and worrying over nothing. What do you think? Thanks again!

If your measuring ahead, thats a good thing, the bottom line is as long as your at least measuring at O date, it doesnt matter at all...
ETA- you can have AFP as early as 12 weeks...Although thats not standard practice....and as late as 20 weeks.
