I had a baby 3 months ago, she was 4 weeks premature but with no complications. About 3 week s ago, I had severe abdominal pains down my lower left side and passed dark plum coloured stools followed by blood. I went to hospital but was sent home. The next day I started to have Brown mucus discharge from my vagina, it was a very small amount and only when I wiped after going to the toilet, the past couple of days it s gotten a lot thicker, like small clots sometimes accompanied with a small amount of bright red blood! I should also mention that about a week before all this happened, I took the morning after pill, I don t know if this is relevant.
