How can I alleviate hip pain?

I'm just a few days shy of 16 weeks and I'm plus size so I already have big hips (or at least I think so). I take tylenol before bed so I can manage to get somewhat comfortable when I lay down. Some days it doesn't hurt at all but some days I feel like a little old lady struggling to get off my couch. It doesn't help that I live in a two-story house and climb the stairs a few times each day. 🙄

I've tried the pillow between my legs/knees but end up pushing it on the floor at some point in the night lol

Any suggestions are greatly appreciated. 💜
