confused what day did i get pregnant..

Hi would anyone have any idea which day I concived all the ovulatiobln calculaters are saying different dates.

I get my periods every 3 weeks, 21 days my last p was on the 23rd of December It lasted 5 days so 23-28 but I had intercourse on the 29th a day after I thought my p finished, but noticed some blood after intercourse. Then had sex again 2nd of Jan about 4 days later.

My question is did I concive on the 29th of Dec or 2nd of Jan.?

Sperm can live up to 5 days, or 7 days in the most ideal circumstances. Unless you're tracking your ovulation the way people do when they're trying to conceive, it's impossible to say within that week to say when exactly you conceived.

Thanx girls. But could the sperm from the 29 have lived inside until like the 1st of jan the next week even if I was still bleeding a little on the 29th an got me preg b4 the 2nd.

4 days really isn't enough of a separation to know when exactly it happened. At best doctors and ultrasounds can give us an estimate, although they could be up to a week off, even at their best guess.

Its hard to tell exactly when conception happens, but chances are you didn't conceive the day after your period. It'd probably be the week after your period since you have a 21 day cycle.
