For the past two months I been feeling nauseous, light headed, having headaches, cramps, backaches, and chest pain, I was urinating alot but that stopped after I took medicine for a uti, it didn t clear up the first time so I had got prescribed more for a uti and the urinating alot stopped... Now I still have all the same symptoms except urinating alot. I had unprotected sex October 29. Then I had my period 4 days later but it wasn t due until another 3 days. It was kind of unusal but not really it still looked and felt like a normal period. The night my period went off , it stopped then a few hours later I went to use the restroom and i was bleeding lightly. So I put on a tampon and the next morning I was bleeding I just had brown blood on the tampon... I don t know what s going on with my body...
