Hi...I have had GERD long b4 I got pregnant with my DD and I was ok....I got thru it and u can too.
I kept packs of dry crackers with me when I had my nausea which was the pregnancy....but, it also helped with the GERD/reflux too.
I elevated the head of my bed, which in later months of being pregnant helps as it is hard to lie flat with a big tummy.
And it also helps the GERD issues......
Avoid the foods u know r ur triggers, and keep a journal as they may change once u r pregnant.
Try to step off ur meds slowly with the aid of ur Dr.....tell him that u want to become pregnant and it is best to not be on these meds for too long.
Diet and exercise...can help u with GERD...also knowing what ur root cause is...I have a hiatal hernia...that is my root as well as a few other medical issues...but know what urs r and u can deal with these with modifying diet and lifestyle.
Good luck : )
