Hi so I'm 29 weeks pregnant and have been experiancing some tightening and quite sharp pains also feel like I need a massive poo (sorry for the tmi) I had what I thought was servere ligamen pain earlier and when I went to the loo I had a brown sorta old blood discharge but similar to what I get with my cervical erosion so thought nothing of it but when I checked I couldn't feel my cervix and now I can feel the tip. I've also been feeling kinda off. Any ideas please?
