Heartburn

Alissa • Expecting baby #1 in December and we couldn't be any more excited!♡
I just started my period yesterday(actually on the day I was supposed to start, which is surprising because normally I start a couple days after it says I will) and I've been having heartburn for the past three days...does anybody know of a natural way to relieve heartburn? I normally don't have heartburn but this is like toe curling! It doesn't last very long, but it comes in spurts.
