I had SPD with no.2 although it was 'picked up' late(I told MW who said pain was normal, saw a temp. MW who diagnosed but too late @38/39 weeks). I was pretty housebound at the end and TBH forgot just how horrific it was. I felt the same thing starting at 20 weeks and got a form to give to the physio unit at the hospital, but still at 32 weeks I have heard nothing. I will chase it up tomorrow as I am guessing it shouldn't take that long, but, it honestly feels like my pelvis is going to crumble. Not very very sore, actually snap apart. Please can someone tell me I am bonkers and painful as it may be, this never happens...?
