Update - called my doc and as i thought she's off today so i still left a msg as she's often in on her days off or will call me tomoro. It's getting better for now so unless it gets worse i'll leave it till tomoro, if it gets worse i'll call the hospital. But i was thinking, i did yoga for the first time yesterday since preganant(teacher did yoga through her entire pregnancys so knows how to be careful etc) but maybe thats what caused it?? Fingers crossed that is all.
