Hello! Okay here goes.. I'm 30 weeks and 2 days pretnant today, my due date is September 21st 2016. My last period was the 16th December 2015 i have a pretty normal cycle 26-28 days never any longer, i have been with my boyfriend for 5 years nearly i slept with him from after my period finished right through but i daftly went out one night on the 9th Jan 2016 and had sex with someone else! i know really really daft no point saying we were going through a hard patch and he was making me feel unhappy because thats no reason to cheat i know. Don't need people to tell me that as i already know and cheatings never right EVER never thought i'd be here, but is it possible to have had sex on the 9th Jan 2016 and be due September 21st 2016 ? little bit of advise would be great thanks, beating myself up every single day praying and hoping my baby is my partners.
Hi Emmax,
Your due date is 40 weeks from your LMP. That is how doctors calculate it with a known LMP. Nobody, not your doctor, nobody, can tell exactly how far along you are. It's all estimates.
You had sex on/about day 24 of your cycle with "someone else." At that point, you'd have already been pregnant.
You'd normally ovulate between days 11-16 of your cycle. The egg can remain viable for up to about 48 hours. So, you'd be about 6 days to late to have gotten pregnant by "someone else."
Hope it helps.
