Does anyone else have a really sore back? I'm only 5wks6d. My back is really sore on one side mostly. I did have some ligament damage a few mths ago and this pain is in almost the same place so wondering whether the pg is irritating that, or whether it could be sciatica. It's around my lower hip and seems reverberate to my hip a little at the front. It's not so painful I need painkillers but its been pretty constant today, coupled with the worst exhaustion I have felt so far. You don't think it's anything to worry about do you?
