feeling nauseous w/ a mix of heartburn?

Cora • baby boy coming may 2020💙

hey, i’m currently 29 almost 30 weeks and over the past two weeks i’ve been getting a feeling of throwing up but it also burns at the same time? idk i’ve tried tums and that kinda works but it wears off after an hour or so. i was just wondering if anyone else has had this issue?
