I'm 39 weeks and 3 days. I have dropped more since Monday, and right now my lower back is sore like I've been lifting heavy things which I haven't all i have been doing is some standing to clean. And sometimes it feels like I'm holding my stomach in but I'm not. And sometimes if feels as if my back is using its muscles to lift if that makes sense. But only my lower back. I've had pains like stomach ache but they subside and it feels as if I need to poo but I can't go lol.
