I had heartburn terribly at 15 weeks. The doctor told me to take Pepcid, but it didn't work. My friend told me to try MILK and it was a lifesaver. Someone else suggested eating a tablespoon of mustard; she said it worked with all four of her kids. I didn't try it, but I heard from a few people that works as well.
Ob gave me prescription for zantac ( but u can buy OTC) lifesaver truelly thought I could breathe flames for awhile there:)
As the above comment says MILK!!! I have only just started getting heart burn the past few weeks, milk has been my savior!!
Drink milk it always helped me I haven't had heartburn this time thank god. But my nausea is off the charts everyday!!!
