@Jennifer it’s stared middle of the night out of no where but was only by my shoulder area now it’s like my whole back mainly middleish
I feel like the way we sleep changes so much as we gain belly.. it’s gotta affect our muscles
That can happen it's common thing when ur belly gets big it pulls and strains meny muscles
I’ve been getting this too (35wks). The heating pad does wonders to help relax the muscles
