Kinda confused

Devynn • Momma of a 7 year old girl & a 4 year old little boy & currently expecting 🥰

Has anyone ever woken up and had a weird feeling in their chest on the left side? Is it cause I was laying on my back during pregnancy?? I’m confused it wasn’t unbareable but made it feel weird to breath till I changed positions then I was alright.. kinda worried now .. always have been the type to have health anxiety especially about my heart
