Hi! My name is Lauren, I'm 20 and I need your help! I am 4 days late on my period. I had sex 2 weeks ago, and we put a condom on only a few minutes after we started. I understand its not safe, and I'm really worried. Last week, my boobs got very tender and I started cramping up as if I was getting my period. I am always tired lately but I think that's due to college and work lol. Help!
