Answer 1

Penicillin doesn't seem to affect a woman's period. There may be some other factors that can cause this. Oh and if you're taking birth control, it can cause delay or advanced period. A note on penicillin and birth control: doctors usually advise all women to use a condom or other backup method of birth control while on antibiotics since antibiotics can interfere with the effectiveness of birth control pills.

Answer 2

Probably just an early period. Do you usually have irregular periods or is it always a certain number of days?

If it's usually a certain number of days, then tell your doctore. But either way, tell your doctor just to be safe.

Answer 3

PCN doesn't cause vaginal bleeding.  But you being sick and needing an antibiotic may have stressed your body thus causing some spotting or an early period.

Answer 4

Some antibiotics can decrease the effectiveness of your birth control.  I'd take a pregnancy test in a few days.  The light bleeding could be implantation bleeding.  Are you sexually active?  That was my first thought..
