Concerned question

I'm newly pregnant from a mc back on the 4th of July. I have two living children that are amazing that I was even able to carry to term let alone have. I've had two mc as well. I have pcos as well as an inverted cervix so I have issues already. I just got home from babysitting my friends two kids, 14 and 7, and had some issues today that got out of hand with the 14 year old boy. Very stressful and stranous day needless to say. I'm concerned if I should contact my obgyn or go to the er, for the past hour now I've been have sharp pains in my right side like towards my ovary. It's only when I move, cough, breath hard, and talk. Please help with some information me and my family can not take another loss like this!
