Can I use Zithromax or amoxicillian for a Vaginal bacterial infection

I currently have a vaginal bacteria infection, I know this because I have had them before.

I would like to know if I can use Zithromax tablets or Amoxicillian to make it go away.

The doctor in the past has given me Flagyl but I don't have insurance and can not afford to go to the doctor.

Thank you
