I think it was around 2 months ago that I experienced dark brown discharge. I had it for about 3 weeks. Nothing heavy, just simple spotting. And then it stopped. Now I am having the same thing except this time it came 3 days before my period. I don't believe its anything serious. I just think that its a sign of old blood. I am on birth control so maybe that could be affecting it. I'm not completely sure. When I went to the doctor yesterday,
(very professional doctor) I asked her what it could be and she said don't worry its normal. Another thing I was concerned about was the burning sensations I had when I went to the bathroom. Again, it could have just been a urinary tract infection. It lasted for a week but it never happened again. I think many of these situations happen for me because my immune system is very low and its very easy for me get infections. So I'm trying to build it up. Other than that, my doctor said my blood test results were very clean and I have nothing to be worried about.
