I am 16 have been having stomach cramps, sore boobs, enlargement it seems in my boobs, headaches, nausea, fatigue, more moody, and I've experienced going to the bathroom more frequently. My last period started on December 3rd. I had sex on the 17th it was safe because a condom was used. And i have just recently started spotting the bleeding has gotten heavier. Like I'm on my period, but its two weeks early. I have never experienced PMS this bad. I'm cramping extremely bad all i wanna do i lay down and sleep. My stomach is bloated and has felt really tight here lately. These symptoms have occurred for a week now. Please help. I need advice on what to do.
