Just woken up about 15 minutes ago.
The pain is excruciating. It feels like extremely bad period pain but all the right hand side - Lower abdomen.
My lower belly is all tight.
If I press right hand side of tummy gently, I want to yelp!
This is normal ligament stretching, isn't it? The pain won't go away.
Any ideas? I feel a fool but it feels like I really need to pass a stool or something, except that I don't and the pain is all in the right hand side of tummy and is like period pain if that makes sense? 
Very different feeling to trapped wind
