Melody • Wynter Rayne 11.2018♥️ Married to my best friend♡😍 Gunner Tate due 2022

im 25 weeks preggo and I'm having pains in my lower back basically on left side only behind my rib. and chest pains. I've honestly never had gas pains so I don't even know if this is right or not but, what do gas pains feel like? I thought maybe it was heartburn but, took meds for it and still have this pain. super worried. ftm here and sorta freaking out....
