In regards to pelvic instability, i am experiencing the same problem, im only 29 weeks and have had it for awhile now.... i would still like to know if there are any negative effects during labour as i was talking to a friend of mine who experienced the same issue during her pregnancy and her labour was really bad to the extent that one of her pelvic bones fractured and had to have an emergency ceasar... this is my 2nd preg, and whilst my 1st was very blissful and easy im very worried and even thinking of opting for a ceasar for this one.... can someone please help as its stressing me out...i have been told by my doctor and obs to rest and been reffered to a physio.... i dont know what else to do...
