Hi. I have been having this brown vaginal discharge. It changes its consistency. Sometimes it is light, sometimes it is dark. I got on July 9, 2018. I thought I am about to have my period. But I don't think I did because the brown discharge lasted for weeks. It only stopped last July 22, 2018 when I had pull out sex with my boyfriend. But last August 5, 2018, the brown discharge occurred again. I'm not sure if I had my period on July because of this, and now I'm still having it. I'm afraid I sat on a toilet sit with sperm on it and I touched it and accidentally touch my vagina, last august 3. Am I pregnant? But, the brown discharge started on July 9 where I did not have sex before that. I'm just afraid I might be. If not, is this normal?
