I took plan b 36 days ago (i have it logged). The condom broke and my boyfriend came inside of me. We haven't had sex since then because i've been so scared. Well after taking plan b my period came as expected two weeks later. After i ended i thought everything was fine but a week later i started another period. I'm pretty sure this is just a side effect because the whole 7 days that i was bleeding it was dark red or brown. It has been a few days since i ended that period but i woke up this morning having light bleeding and minor cramps. Any idea on what is happening?
