Not sure hun, but could it be a touch of SPD?? My pelvis is getting worse by the day - I nearly missed my stop on the bus today because I couldn't get up, I had completely seized up!! Not sure about head down - my little one is definitely still on the move - one day he's kicking me down low and the next he is up high,the other day I'm sure he was lying crossways!! In hospital the midwives nicknamed him 'wriggler' cause he was so active when on the monitor and he's still really active now! Hope it's just normal stretching hun and not too painful xxx
