Hi!
Anything is possible! In my years as a doctor, I have seen all of the scenarios. I have seen moms really sick with number 1 and fine with number 2. I have also seen moms really fine with number 1 and very sick with number 2! What I have noticed is that even if they are sick again with number 2, they seem to tolerate it better. Maybe because number 1 keeps them from dwelling on it, or maybe because they now know that it is only temporary. ( I remember wondering if I would ever feel
normalNormal saline flush again!).
If you do want another healthy child, you should not wait too much longer, but your chances are probably quite good despite your age.
One other thing to consider, is continuing to take your medications through pregnancy at the lowest
effectiveEffective strength cough syrup dose, and then bumping that dose up again as soon as the baby is born. That may help to reduce the symptoms on the second go 'round.
Would you ever consider adoption? I guess technically that's "cheating" but, it might be a wonderful answer for both you and the baby!
Good luck!
Dr B
