Low abdominal pain - constant cramping

Hey guys - 32 weeks and 2 days pregnant. Woke up this morning with a painful cramp on the left side of my abdomen. Just figured I slept funny and needed to stretch. Now this evening, my whole lower abdomen is sore and cramping. I don’t think it’s contractions because I’m able to move around and talk and do things. Maybe Braxton hicks? Thought those would be higher up. But I’m a first time mom so I have no clue what to expect. It’s just so tight and uncomfortable and he just seems so heavy. He’s moving as well!

I am curious if I can use a heating pad or Tylenol to help relieve this pain? Or is it something I should contact my doctor about this? I think if it keeps up tomorrow I will. Thanks!!
