Lower back pain??

Christy
Ok so yesterday my boobs started feeling really tingly and sore last night I started having pain in stomach that made me feel sick but I didn't vomit. Came home and slept but had really bad back pain from mid back down that is constant (kinda feels like extreme period cramping.) I am only 33 weeks so I don't want to run to hospital bc I've read alot of women have lower back pain. Trying to see if I move around if it will subside.
