"so me and my gf had sex  and the condom ended up breaking. so 20 hours later i bought her a plan b. i suggest eating a good big meal while taking it. she didn&#039;t really have any symptoms after she took it except her stomach started hurting. her period wasn&#039;t due for another 2 weeks. it ended up coming a week early. brown/dark red blood for a few days then cherry red blood. just be prepared and responsible. take care of your girl while she&#039;s on it make her feel loved and important. understand and really listen to how she feels. just pray and everything will be alright thank you god!!"
