Im 21 years old. About a week ago, I was around my grandmother who was sick. For the past 2 days I have felt bad myself. Not thrown up, but very nauseated. Very bad stomach pains. Weakness. Very tired but cant sleep. I had sex in early Feb. but not since then. I keep worrying Im pregnant. My periods have been messed up (but pretty much have my entire life). Ive taken 2 pregnancy tests and they were both negative but I keep stressing over it. Im really scared because I dont want a baby. I am on birth control. I have also been urinating alot more than usual. Like, 4 or 5 times an hour and I really have not drank anything. I am a high stess person. Everything stresses me out every single day from getting to work on time to making sure everything is done before I leave. I also have been diagnosed with and Ovarian Cyst syndrome. Im just in alot of pain right now and really scared. Can anyone give me some advice and ease my mind please??? :(
