Left side pain

I’m 19 weeks pregnant. I woke up almost in tears. Two inches above my left hip was hurting so bad. It seemed like the pain extended to my leg. It is directly on the side of my body.

Yes I could go to the ER but I really feel like it’s a pulled muscle. I got up and walked around and it got better. I have no pain in my abdomen.

What would you do? I really can’t afford an ER visit for them to just say it’s strain or a pulled muscle but I do want everything to be ok.
