Omg. Exciting! Real contractions stop you in your tracks. There really is nothing like it. I remember walking along the hospital corridor and having to grab onto the wall. My knees wanted to give up. Dull punch in the gut kind of pain. I'm pretty sure I swore out loud :)
I'm 39 weeks and 4 days I think that's my mucus plug
It feels like really bad menstral cramps and bad gas pain together. I don't think that's normal, you should contact your Dr or midwife anytime you are bleeding.
