I am 34 year old and couple days ago, after sex, I started to bleed. At first it was drop or two, on day two it increased to bleeding where I had to wear a pad, on day three I noticed a lot of bleeding and big clot came out. I have no pain, just little cramps but nothing too serious. To add to this I recently been diagnosed with Hashimoto disease, I do not know if that is related to anything that is happening to me but, I thought you should have all my medical conditions.
