A friend, had sex with her partner last weekend......unprotected. (friday) took her period yesterday...thats too soon to be safe isnt it?... I thought it was...cos she had the morning after pill few weeks ago and this is her first period from that ....xx
My ex bled for 3 or 4 months with one of our daughters and was indeed fooled into thinking that she wasn't pregnant for some time due to the absence of morning sickness etc as well. I'd take her to be an intelligent woman in touch with her body and it's usual behaviour but clearly being a bloke I can't comment personally.
