Hey guys, I’m 15 days late to my period. The last time I did anything sexual w a guy was March 10th, and I was wearing clothes the entire time but I’m afraid that the semen might have seeped thru my pants into my vagina. I’ve been feeling like I’m getting my period for like two weeks now (bloating, fatigue, gassy, cramping) but nothing! I took two pregnancy tests a couple days ago, and they were both negative. What could this mean? I’m really scared.
