Probably a little TMI, but we're all pregnant here!

39 weeks and 5 days here. At my appointment I was 50% effaced and 1cm dilated. Super, right? Only been at 1cm since 36 weeks! Anyhow, this is the TMI part; Last night for a solid 30 minutes or so I could feel the little bugger bearing down, what seemed like as hard as he could. Oh, my, was it a bit painful! But at one point I felt everything up in there shift downwards for a little bit, and it felt as though he might just pop right out, along with my insides! Thankfully that feeling went away. Today, everything feels so swollen and achy in there I can barely walk. 😴 Anybody know what that was? It seriously felt as though he was trying to push my insides out of me!
