2nd opinion maybe? Constant cramps

Anyone else? I saw a dr recently with my ob‘s office and she didn’t take much time with me or really listen but I constantly cramp. Like it hardly ever eases up. My front area and the back. I cramp like annoyingly all the time. From the time I wake up until I go to bed most days. Even when I’m doing absolutely nothing. Should I get another opinion. Something has to be making me cramp. 30 weeks and a few days along now.
