Sounds like normal pregnancy pains and round ligament stretching, as long as you aren't bleeding its probably fine but maybe just call the doc to be sure. Phone calls are free hospital visits are expensive if it's bad the doc will say so
Hi, I think lower back pain is normal in pregnancy. As long as you aren't bleeding, everything should be fine. If going to the hospital will reassure you, then you should go :) To stop your worries etc. Let me know how things go etc.
