I m an 18 year old female on birth control. my boyfriend and I have unprotected sex very often and rely on the pill. I recently had sinus surgery and went on an antibiotic and steroid, and had my period right after surgery.. since then I have had some weird symptoms/or side effects. it started with sweating, almost all the time even when resting. then I started having to use the restroom more, and I even wake up in the middle of the night to pee. I do get headaches and feel nauseous. I ve had a serious increase in appetite along with a bloated abdomen. I m starting to experience cramps, but am also tender to the touch on certain parts of my stomach.. what should I do?
