Does Intake Of Azitrocin To Treat Chlamydia Cause Longer Periods?

about 2 weeks ago i took one dose of azimatricin its hard to spell sorry.. But i had chlamydia and i took them pills 500mg each one dose... 2 pills. Starting april 19th I have been on my period.. So for 9 days now, and my period was never that long and i dont know if i should be worried or just wait until its gone. I dont know if it could be the pills affecting me period or if they didnt work n i still am infected. im not in any pain when intook the pills my symptoms went away but im still not sure if it treated the chlamydia... I was going to go to the clinic on thursday but i dnt know if my period is going to be gone to see if i need to be retreated for the infection again...im not in any pain it just feels like a regular period im so confused
