Can antibiotics affect periods?

[scared4210]

Over the past 3 weeks i've been on a z-pac, amoxicillin, a liquid form of azithromicin, and had two shots in my hips for tonsilitis.  Today I started my period and I'm not supposed to start until around the 28th. Some people say some antibiotics can affect your period and some say they can't.  I'm jw if anyone knows the truth about that?  I never have early periods, always late. and I havent had sex in 2 months and I've had my period already.

being sick can affect your period. it can delay it or it might even come early. i'm not sure about the antibiotics but i would think that anything you put in your body will have some sort of an affect on it. after all, that's what medicine is for. i'm gonna bet that it's probably due to the fact that you've been sick. sickness is a stress to the body and can cause as i stated above, your period to be late or come early. hope you get to feeling better!!

Im not on birth control, im just wondering why my period is so unregular. I know it might be stupid to worry about it, but I just know my body.

I don't know if it can affect ur periods but it can affect the effectiveness of your birth control.  So if your on birth control, and you might have sex, just use a back-up form of protection.
