Please tell me what helps you if you are suffering severe pgp. This is my 2nd pregnancy. My pgp currently is zoned in on the groin area and I'm crying every evening I'm in so much pain. I've got a support belt I wear daily and I'm waiting for physio at the end of the month but it seems so far away, I'm afraid it will come too late to make much difference. The mw just tells me it's 'normal'. 
Even night time is painful as it flares every time I roll over, I do keep my legs clamped together but it doesn't seem to help. If I stay in the same position too long it's v uncomfortable. I'm 30+5 and feeling pretty desperate
