I'm 36 weeks and I can't take this anymore 😭😭😭😭 nothing helps it's this constant searing pain in my chest I can hardly sleep because as soon as I lay down it gets worse. Tums stopped working months ago so now I'm taking Zantac but it's providing no relief tonight I'm seriously miserable.....
What works for you guys? I'll try anything at this pointÂ
