So I feel the baby moving and she moves a lot and I know everything is ok. But I been feeling like this soreness cramp like in my lower belly. and in my back a little bit, I think it could be how I slept for my back lol. I know it’s probably my round ligament. I’m calling my doctor on my lunch break but just need some advice till then. It is normal right? It just feels the the muscle is sore
