Heartburn?

👩🏻

Is anybody else having weird heartburn? I never get heartburn so I’m not sure if it’s that. I get this pain below my sternum now and it progresses in intensity until o also have referred pain in my back. The pain in my chest also goes downward a bit from my sternum. I’m not having any pain in my throat. Tums isn’t helping. I lay on the floor in the bathroom for a while suffering until I vomit and then feel better. I’m 14 weeks and haven’t had any vomiting early on and my nausea has just subsided and this is different. My first pregnancy was not like this.
