Lower back pain all day

Erica • Sat, Aug 11

I’ve been getting pain in my lower back all day painful and uncomfortable. (TMI) Feels like I have to poop but I don’t and also starting to feel some cramping in the front bottom of my belly. I’m only 20 weeks could I be going into premature labor?? I still feel the baby moving so I’m assuming I’m okay but I’m not sure ☹️
