I'm not sure if this is the best place to post this but I just want some advice.

I think I pulled a tummy muscle last night in bed. I went for a wee, got back into bed and laid how I would normally - half on my side and half on my belly with my leg out to the side (I hope this makes sense). After a while I stretched out and rolled over. Half way around I felt this massive pull in the side of my tummy just above the hip bone. It really really hurt. I managed to roll onto my side and after a while the pain went away. I'm not sure what happened but I remember feeling what I thought was flutters after I got back into bed but now I'm thinking that maybe it was the muscle contracting after being stretched out waiting for me to wee and then rolling over stretched it out too quickly.

I'm going to try and hold off seeing anyone until tomorrow when I have my appointment with the hospital so hopefully everything is OK. I'm just a bit concerned now. Has this happened to anyone else?
