I am pregnant with my second child, and for both pregnancies have had to deal with a chronic cough morning, noon, and night. My first OB had me see an ENT specialist who diagnosed me with LPR, a type of acid reflux that does not produce heart burn. It does, however, produce a great amount of phlegm and this real stretchy, sticky clear junk. This makes me vomit often. I am taking a low dose of Nexium and I tried Protonix for the first pregnancy. I didn't want to take meds. but I was coughing so much and spitting up junk that I would have had to quit working. It was really gross, and still is sometimes. Do you have a hairy throat or mouth feeling? This sensation is also part of LPR, which luckily is taken care of by the meds. I still get days where I cough so much I can't breath and I have to sleep upright in a chair. I am now 6 months pregnant. I cought for 9 months straight, and it's hell. I feel bad that you are also dealing with a cough. People are constantly asking me if I am o.k. It's embarrassing. I tell them, it will last until I have the baby. Pregnant woman get GERD or LPR because the hormones cause the sphincter muscle, which keeps acid down, to weaken. The acid gets up. LPR occurs when the acid is very high up into the larynx. Your voice can be raspy and it is difficult to sing. I couldn't believe that hormones were making all of these strange symptoms happen. My bad luck to have the issues for both pregnancies. For your sake, I hope your cough doesn't last the entire pregnancy. If it does, just think, your not alone, and you can safely take meds. Ask your doctor. Good luck!
