I'm about 9 and a half 10 weeks pregnant and started to get a bit of discharge which was a pinkish colour like it was mixed in with blood. Then as the day progressed it got browner and turned into a redder colour. I had a scan at 7 and a half weeks due to spotting and I got told that the bleeding was from a irritated cervix and I heard baby's heartbeat so I know it was there. Is it possible that my cervix is more irritated or opened and I'm miscarrying?
