Im 17 years old about to be 18 in 3 months and I got off my period 6 days ago. I took plan B on the last day of my period which was december 25th and starting on the 29th i had soreness in what seems like right above the ovaries, a pain on each side of my abdomen. I also have this pulsating around my belly button and it will shoot down to the right side then give me back pain. I also have headaches and have gotten easily hot and overheated during the night. I know im not pregnant because ive testes and JUST came off my period and it was normal. Could this be my apendix? UTI? I had a UTI about 2 months ago could i have another? Oh and i feel like i have trappe gas and it travels all over my stomach.
