Ok so first off I was on birth control for a month and half nonstop due to changing birth controls and I was spotting brown discharge the whole time I was on it I did miss my birth control two times but followed the instructions to take it when I remembered. When I finished the pack on a tuesday may 22nd the next day wednesday I stopped bleeding until late that night and started having brown spotting again all the way up until saturday when i started having a very light period with red blood until wednesday may 27th i only used about 3 tampons a day and none of them were full infact not even half full. Anyways i stopped taking the birth control because i didn't want to bleed anymore. Now im suffering from mild period like cramps in my lower abdomen, upper abdominal sharp pains under my ribs that come and go, every once in a while im getting shooting pains in my mid lower stomach, dull lower back pain, headaches pretty much every couple of days, my discharge is white, thich and creamy, i keep getting a burning sensation in my left breast, i feel nauseous everyday and all i wanna do all day is sleep because im so exhausted from nothing, also i feel like im sweating in my air conditioned house. Yesterday I went for a walk and could barely walk i felt so nauseous and was getting a sharp pain in my back. I've taken 4 hpt tests and all came back negative but still feel as though im pregnant. If im not pregnant what could all the symptoms be from?
