Terrible heartburn!?

Arianna • With the love of my life and mother to our handsome little boy ❤️
Hello, I am 22 weeks pregnant and suffer from really really bad heartburn. It usually hits me bad at night, I take a couple tums and try to sleep, but now it's non stop and really bad! Tums don't work, and I feel so crappy. Anyone else has super bad heartburn? If so, what do you do for it to help you?? Thank you!
