I just found out that I was pregnant a few days ago. I have smoked for a couple years but am going ti stop soon. I am pretty short of breath. I have two other children so I have been pregnant before. I am a little worried because I'm so short of breath. I don't have my first Dr app for a few days. Could there be something wrong?

Could be a cold or something, or just the effects of smoking. If it gets any worse go to the ER. This is a bad one. If you're starved for oxygen your baby will be doubly so.
