So my doctor pretty much told me any minute I will probably Pop and they were even surprised I was still pregnant at my appointment today. I've been in so much pain and tonight seems to be worse. I'm cramping so bad all over my belly and my back is achy. It's weird I feel off. Like something just is different. I'm nauseated exhausted and I feel fairly weak. What do you guys think? Is labor seeming close? FTM this is all new to me.
