Me and my girlfriend had sex yesterday. After the first time, i removed the condom and i think i got some seemen on my hand / fingers. I then proceeded to put a second new condom on so we could go a second time. I am worried that i might have gotten sperm on the second condom and that this might get her pregnant. should i be worried and go buy the plan B?
------ The condoms were spermacide condoms so if that has any effect let me know!

PLEASE
