i had a normal period on March 6th and Another Normal Period on April 1st. We had unprotected sex at the time of that cycle. It is now April 12th and i am discharging small amounts of blood and clots- when i wipe I am also seeing a brown coloured discharge, but only have small amounts of discharge on my pad. I have some pain in my lower back on the right side. I took a home pregnancy test and it came out negative. Could I be pregnant or is this a miscarriage. Or could this just be stress thinking about it. I have one child and I have one miscarriage. The last time I had a miscarriage. There were large amounts of clots. I had to puke and c**p at the same time. I went home and finally when the large clots had passed. I was better and back to work the next day. This was in the first month however, before even missing a period. My concern is that I may have a tumor on an ovary. I am 29 and 245lb.
