Pelvic pain

Mercedes

I’m almost 20 weeks. Since yesterday I have been having pain along my pelvis area. It hurts to move and to press in the area. I stayed home from work today thinking rest would help, but it hasn’t. When should I call the doctor? I don’t want to be that first time mom that calls the doctor over everything. Is it possible that it’s just round ligament pain? Everything I’ve read about round ligament is that it isn’t constant.. And this pain is.
