I have been taking Junel Fe 1/20 birth control pills for 2 months but 1 week ago I did not take the pill at the same time every day due to forgetting. This week I have been taking it at the same time every day. Last night my boyfriend and I had sex 2 times. the first time was with a condom but the other was not, enough though he did not ejaculate in me he did not pee in between the two times we had sex... due to still might having sperm in him from last time do I need to take a Plan B pill???
