Okay, so I had unprotected sex June 2nd. I tested on June 11th and 12th and they both said negative. I know that it was probably too soon, but I also received my period on June 16th. I was getting sick before hand, my breasts grew, my nipples got darker, my breasts hurt and I had a slight fever and fatigue. Now that I've had my period and it just ended on the 19th, my symptoms have returned. I just want to know if it's pregnancy or some serious PMS. Please help?!?
