Is anyone on? Dealing with awful heartburn

Your period can cause heartburn/acid reflux right? This has literally never been a symptom for me before but now I've been struggling all day.

I already took a Tums and drank a lot of water but it didn't help, now I'm eating bland crackers and sipping on miso soup

I've never been sick or even gotten nauseous from acid reflux in my life before but it's also never lasted this long. I'm really scared
