Last night, around 2am, my girlfriend and I had unprotected sex and I came inside her (not wise, I know, but it happened). She is on birth control, so normally this isn't a problem. However, the last two days, instead of taking her pill at 10pm, she forgot and took them around 10/11am. She takes Levinogestral and Ethynol Estradiol ( .1mg and .02mg, respectively) pills for 21 days and then the 7 day sugar pills. Should we take Plan B? Thank you all for your help.
