Left side pain

I’m 23 weeks

I have been experiencing pain in my left side for the last 3 nights. It only happens when I’ve been laying down for awhile and it’s the worst when I try to switch from my right side onto my left side. I can feel the pain in my groin, left hip and down my left leg and sometimes my back.. This seems to mostly happen at night When I am laying on my sides and it goes away after I have been standing or sitting up right for a little while.. I’m just wondering if this is normal ligament pain? Or something else. The pain ranges from moderate to severe and can be debilitating when I try to switch positions.

I’ve read a little bit about Pelvic Girdle pain. Can anyone relate?

I messaged my midwife right before I posted this, I’m just waiting for her response.
