Chlamydia while pregnant....HELP

I am 9 weeks 3 days pregnant. I had a pap smear a few days ago and my results came back normal except it showed positive for chlamydia, I FREAKED out. I have never even had a UTI let alone an STD. I have been with my husband for a year......so this is my first pap smear being with him.....We dated 5 years ago and broke up ....my pap smear after the break up was normal. So we now figured out he contracted it sometime while we were broke up.

The doctor prescribed us with each 1 gram dosage of Zithromax and we were told to not have sexual activity for 1 week after completing the dosage. My regular checkup for the pregnancy is the 3rd week of March and the OBGYN is going to check me out then.

Will this hurt my pregnancy? I'm so terrified
