Try a warm bath and just sit there for like 15 20 min , and see if that helps , it helps for me when I feel serious pain in my side
I'd go to the ER. If they don't help alot depending on how far along you are I'd look into a massage!
Hope you feel better. But if it dont stop or it starts to get worst go to the ER. You shouldn't have that kinda pain. Good luck♡
Try getting on all fours & take bubs weight off your back for a while. It works for me.
If it keeps hurting go to the hospital hope you get better
