So this is the first time I've ever posted anything like this. My girlfriend and I had sex the day after she had ended her period and the condom we were using fell off and I came inside of her. She took a morning after pill the 2nd day after intercourse (the Plan B pill works up to 3 days after) but now she is a few days late. What are the odds that she could be pregnant?

the morning after pill can completely throw off her cycle for a month or three. Feel free to take a pregnancy test just to calm your nerves but you have to expect an abnormally timed period after taking the plan B.

if you had sex the day after she ended her period the likelihood is very slim, most women dont ovulate again until quite a while after they've had their period. I think you're ok.
