I was just curious about if u could figure out ur conception date or the whereabouts. The reason I ask is because I was with one girl one time on March 7th and she had the baby on Dec 22nd but I seen early on that she posted her due date on fb as Jan 12th. I always think that she was with another guy or guys in the same time region though. So I'm always trying to calculate conception dates to figure out if it could be mine or not.

Hi ,jbell, if you want to post this as its own question, we could do some analysis, but it rather sounds from the few facts you posted like she did not get pregnant from the sex on March 7.

Hi wjc2010 did u guys use any form of contraception at the start of March 10th and beyond? 41+4 seems really long to go!

Hi no conception was used after 10th march onwards, doctors here let you go 12days beyond due date, I was booked in for induction on the 22nd, may I ask why?

[wjc2010]

Any help would be greatly appreciated, everything online says I should have conceived around the 19th march give or take a week?

Person B.  Why do you even wonder, if you had ultrasounds plus a period on March 5?

[wjc2010]

Thankyou for answering, just wanted to make sure there was no possible way, worrying too much I guess.

[AnnieBrooke]

All evidence points to person B.

Hi,
Sorry to bother you again. I had my baby on December 21st, delivery paperwork states 41 + 4 days. I just wanted to check this still makes my conception date roughly the same?
Thankyou

It just sounds like all of the above analysis has been reconfirmed.  I don't understand why you keep asking -- you would have to have been 45+ weeks pregnant if you got pregnant from the sex on February 20.  Doctors don't let women go that long.
