I'm 12 weeks pregnant with DC2, today I've got back pain for the first time 
It's not bad enough to take painkillers, but is very uncomfortable! Lower back, feels like I had in late pregnancy last time which I presumed was the weight of my bump. Is it normal to be sore this early, and what can I do to help ease it? Will exercise help? It's a dull pain, not sharp or stabby.
