my dates dont make sense

[jesslee83]

ok so i *WAS* practically POSITIVE i concieved christmas week! but my dr is saying i concieved between january 28th to feb 4th.....and it is driving me freaking crazy! i do look 5 months preg, but i'm only 15 weeks??? i need to take more pics and put them up lol.....but yea i am huge, and he says the *baby* measures only 15 weeks, but is it possible the baby is just measuring small? i didnt have a period in january and according to ovulation tests(a lazy form of birth control lol), i either didnt ovulate in january or it just didnt show up.....idk
has anyone else had this issue? and if so, did you deliver on the original time (for me is 9/17), or the dr's due date(10/25)???

I dont know the answer but I want to bump it to the top.

i had the same problem b/c i hadnt had a period for almost 2 yrs after my 1st son was born...i delivered within 3 weeks of each date i had figured out and the one the u/s showed. best of luck :)

[jesslee83]

so did you deliver closer to the day *you* had guessed or the *u/s and dr* had guessed?

You need to go by the ultrasound date because that is how large your baby is measuring. It can be unsafe for a baby to be born too early or too late. So definitely go by the ultrasound date!

i know i should follow my dr.....but um, yeah i didnt have sex from the 7th(night we celebrated my b-day), untill the weekend before valentines day!!! chris was offshore, home for 2 days then he went to see his dghtr in KY for v-day.....there's no way i could have gotten pregnant 12 days after ovulation, that's when i missed my next period, on january 8th.....1st week of feb, BFN, week after v-day, BFP!

I think the later date is probably more accurate. Usually it takes about one and a half to two weeks to show positive on a test.  Ultrasound dating can be off by a week. So you probably got pregnant at the very beginning of Feb. which puts you at the end of October for a due date. Which would match what the ultrasound is saying.
