Hi E.,
I also developed asthma in my third trimester with my first child. She's now thirteen and I still have the asthma. I remember my Dr's telling me then, that it was possible for it to go away after she was born, but in my case it didn't. I wouldn't be too concerned about any effects on your baby, there are so many medications out there with little or no effect on your baby. I was on several with my second child and there wasn't any problems. Talk to your doctor about your worries and congrats. Hope this helps.
