Sharp pains, uh oh!

Ashley • 25🧸Mommy to 1. Pregnant with baby #2! 9 months TTC🍼
39 weeks on Tuesday and I want to know why I can't walk more than 4 feet without having some serious sharp pains. It makes me stop in my tracks and hold my belly! I was last checked three weeks ago and I was 2cm, I have lost my mucus plug too. Can someone please tell me what's going on?! It's just a sharp pain in my cervix. Feels like it's at the opening of my cervix. Haven't really had my stomach tighten up with Braxton hicks either.
