Hip pain?!

Erica

I know this is probably VERY COMMON but I’m a first time mommy and I honestly don’t really know what’s what. I’m 18w1d today and since like 2 weeks ago I can’t sleep on my right side anymore because I wake up with like severe hip pain. Is it just because of the way I’m sleeping?? Or is it round ligament pain?? SOS!! 💕😘
