Looking for a bit of advice, for the past few hours (about 5 hours) Iv been having back pain and stomach cramping, so bad it's making me feel physically sick. It lasts maybe a minute at a time but it is coming in waves. I'm 28 weeks pregnant, very straightforward pregnancy so far. Not sure if it's possibly BH, I'd heard they weren't painful and I wouldn't have said my uterus is hardening but as this is my first pregnancy I am pretty clueless about what to look out for. Anyone had something like this? Taken 2 paracetamol and drinking some water and got a hot water bottle on my back which isn't really helping!
