Have anyone else had severe heartburn?

I’ve been having heartburn since my second trimester. It initially started off with mainly occurring at night and a roll to the left side with my chin tucked subsided it. But now that I am in my third trimester it seems to have only gotten worse. It’s like nonstop 24/7 burning in my chest. I’ve been skeptical about taking any medicine this pregnancy but are tums safe and do they work?
