U should certainly speak wit ur doc bt it sound's like round ligament pain. It's ur uterus stretching as baby grows. It sent me to the er once bc from 7pm on I was in such terrible pain & my husband was afraid for me & baby as well. After tossing & turning all night I couldn't take the pain anymore & went bout 5am. I thought I had a uti or sum it turned out to be nothing. The pan was nothing like I'd feel in my 2 previous pregnancies. Sharp cramps, period like in my lower abdomen,mostly on left side & it felt sore like I'd been kicked there. Even a cpl day's later. I still have a rough time sleeping, nothing like that night again, tho. I wonder if the pain is bad bc I am very tiny (5'4 122lbs) b4 pregnancy & I've been cut twice. It burns around my incision site often, too. I recommend u see ur doc, drink plenty water, & Tylenol if it gets worse.
