So here's my situation. I had sex with a man Thursday morning at like 7 am and he ejaculated inside me. Then later that night at like 8 I was fooling around with my girlfriend and we use a 2 sided dildo. I had the longer end in me and then we switched and put the longer end in my girlfriend. The dildo was out for a little bit and I was wondering if she could get pregnant. She said she is ovulating but I'm not sure how long semen and sperm can live outside the body. I also take birth control. I want to know of i should look into Plan B. She got her period on april 23rd.
