Hi my gf took the post day pill, a week later she had the psot day period, if i can call it dat way, a month and 5 days later she had her period again. we had sex about a 10 days after that cycle began, i used a condom but it slipped as she was getting off me, i never came. now her period is a week later. my question is, does the post day pill affect the mestrual cycles after taking it? will the pill be making the periods late or early months after taking it? or shud i be worried about pregnancy?
