HI i am a 30 year old women and i have been off the pill of about 8mth as my partner and i are trying to have a baby. My periods are always on time but this month on the 15th day of my cycle i was experiencing pain in my uterus and thought it was overulation until i went to the toilet and found i was discharging brown clots in clear slippery liquid and it was smelly. I have notice that it has stopped as quickly as it started. What could this be?
