Hi sasha
Sounds like your pelvic bone ligaments are floating as such...... as my mum and nanny would say.... have you been doing your pelvic floor exercises????
Might be a good idea to start doing them as often as you possibly can. Also if you are into yoga there should be something in that that might help... if your not into it maybe you can get a cheap book and find something in there that might help
Good luck with it....
