If your heartburn is really bad, I know that Nexium is approved for pregnant women. With my first, I was vomitting from the acid reflux (very painful episodes). The doctor said to not eat at least three hours before bedtime, sleep in the recliner, stay away from spicy/fatty foods, and do not lay down after eating. It did settle down after I strictly adhered to the recommendations. But it returned with a vengance (sp?) quickly after she was born. So I went on Nexium for three months. Same with the second, but I only had one painful episode while pregant, but it did return quickly after she was born. Then I had to go on Nexium again. I had never heard of it returning after having a baby, but the family doc said that it is normal in some women. Hubby's sister in law is pregnant and just went on Nexium for her heartburn. Hope it subsides for you all!
