Awww erin, I am so sorry!!
Yes madeline its completely normal, heartburn can be quite common during pregnancy, especially in the later months.
Have you tried anything to help it erin?
1-eat smaller, more frequent meals
2-remain upright for an hour after eating, lying down can irritate the problem
3-eating yogurt or drinking milk can help
4-avoid spicy or greasy foods
5-try a tablespoon of honey in a glass of warm milk
6-mercurius solubilis 6c three times daily
i hope you feel better sweetie!!
