Any ideas for relief?

Im currently 22 weeks pregnant and woke up this morning with sharp pains in the top of my stomach. Only felt it here and there. Through out the day it’s been getting worse. Now the pain is the top to the middle of my stomach. I’ve tried eating soup, cereal and a smoothie. Taken Tums. I do get back pains between mid and lower back. I’ve sat straight up and Tais on my side. Not sure if I can take much more. Any ideas for relief or should I just call my dr?
