Antibiotics?

Hope

Has anyone taken antibiotics this pregnancy, my husband had mycoplasm, he works in a doctor's office and they tested him. Well now i feel like crap and regular doc prescribed me azithromycin? I'm guessing if a doctor prescribed it knowing I was pregnant it's okay to take? I've been sick for a month, and now everything from my nose to my lungs is green much. I have horrible asthma and I'm afraid if I don't take something labor will be terrible, but yet I never ever wanted to take anything :(
