Rib pain at 38 weeks

Brit • Married to the most wonderful man, have a 1year old and baby 2 on the way in may!!

I have had horrible rib pain pretty much all day for the last few days. I had some earlier in my pregnancy but not like this. This makes me cry becuae of how bad it is. And it's around my whole left rib cage. I know it's from my muscles stretching and not baby kicks. But are there any suggestions in giving me some relief. Praying I go into labor soon and it gets better
