So much pelvic pain!

Today my dog ran out the door and I stupidly chased after her and I think I pulled a muscle.  Now, while I'm trying to sleep, I am feeling so much pain in my pelvic area when I attempt to lay on my on my sides. Im literally in tears and sobbing. I'm due in three days and I hope this doesn't affect the delivery! I guess I'll just have to "sleep" sitting up tonight 😢 Does anyone have any suggestions for relief?
