I'm 37 weeks today and I have been recently losing pieces of my mucus plug. I've been nesting for three days (constantly cleaning and organizing everything) and I had sex last night. Around 45 minutes ago I started having a very deep pressure in my belly (TMI but almost like I have gas but can't release it) it comes and goes but I'm not very good at timing it to see how long it lasts or how far apart it is because when it happens it just kinda dulls and it's hard to pinpoint exactly when it stops. It's in my lower abdomen just below my bump so it not my full belly. I'm a ftm so I have no idea what a contraction feels like. It's also hurting back a lot too. I'm trying not to leave anything out sorry if this isn't very descriptive.
