Sorry your midwife was so late Suffolkmum but great that all is ok and that a lovely bump! Mine is similar!
Just got back from physio. She says it's definitely PGP/SPD and I've the left side of my pelvis wasn't doing enough and the right side was doing too much, so when one leg does something the other isn't doing, it makes the bone twist and causes the pain. She didn't say whether the pain in my left bum cheek was the same or not, we just went round in circles. I think it's a trapped nerve. I've had it since October and it just feels different. They don't believe in pregnancy belts too much so she didn't want to give me one as apparently it can be counter-active from when you give birth ( the muscles have been told what to do instead of figuring it out themselves! So I need to get a gym ball (she went to get me one but the gym was being used for a course or something do she couldn't/didn't go in!) never get a freebee! Wanted something for the £2.50 parking fee! So I've got some leaflets and exercises. I know I could be on crutches and it could be worse, but it still hurts and the pain is worse at different times, so of course she didn't see me walking that badly. Hey ho! X
