Bad rib pains.

So, I'll be 27 weeks on Tuesday and I've been having rib pains on and off for a few weeks. But they've been bearable, just annoying. Well today, I've got them way worse than usual, mostly on my right side, underneath my boob. It hurts to even take a deep breath. I took a warm shower, some Tylenol and laid down. I've had an ice pack on it, on and off for about an hour now. Is there anything else I can do to ease these pains? Thanks.
