I am 38 weeks and wondering if I have SPD. I feel very 'saddle sore' on my sitting bones (left hand side only). I have been feeling v uncomfortable in bed for the past few nights- finding it increasingly difficult to turn over without pain. Then last night I slipped on a puddle of water in the bathroom and did the splits. Lots of pain immediately and since then have been very uncomfortable. Rolling over in bed is impossible- had to get DH to roll me this morning from right to left side so I could put some ear drops in!! Also need help getting up out of bed. Walking uncomfortable (feel like I have a bruise, as if I have been riding a bike with a very hard seat). Could this be SPD?
