Right side pain

I’m 34 weeks 1 day and for a little over a week if I lay down on my right side I have pain. Almost like a pulling/tearing pain. My son had been mostly on my left side the whole pregnancy but within the last few weeks he’s moved over to my right side. Now sometimes if I move a certain way or take a deep breath I’ll have a quick pain. I just had an OB appointment a few days ago and everything is fine. I do have Braxton’s that can be pretty bad but this doesn’t feel like a Braxton. Any ideas what this could be?
