hi seems you have done the right thing but it could be stress causing her to be late or even missing a period or it could that she is just missing her period some women can do this and yes it does cause worries. look all two of you can do is wait. have you thought of doing an hpt just to see? do hope this helps. good luck
plan b one step couple days before period could my girlfriend be pregnant? . my girlfriend said she had her period on february 24. so we had sex on march 22nd and i came in the condom and when i pulled out the condom was still inside of her so like 5-10 seconds later she got it out and the cum was still inside of the condom. but we're worry that some may have dripped while it was inside of her. so about 1 hour half later maybe two hour she took plan b one step. and today is march 27 almost 28 and she still haven't got her period i'm really worried that she's pregnant.
