ok so me and my bf started to have sex w/o a condom but then he put one on shortly after that. then about a week or so after i get my period like im supposed to but this time its very light and it ended real quik. now i get cramps even tho im not on my period anymore and im not supposed to get it again till around the 25th; i was just wondering what you guys think could be wrong or why i feel this way?
