Can antibiotics delay a girls period?

I am 19 years old. And m time has never be regular since I first got it, but this time it's deferred for more then a month. Do you reckon that the reason for this could be the two types of antibiotics that I be taking until today? I was taking Ospen from 1500mg, and Klimicin, beside no brake in between. I appreciate any assessment on this.
thank you for your time

Did you own unprotected sex while you were taking the antibiotics? Because if you clutch birth control the antibiotics will override the birth control pill, and make them not work. So you could be pregnant.

How do u prevent the torment?(only females plz)?

well unless you are not pregnant, yes medication sometimes interferes with your cycle. so first do a pregnancy audition if there is the slightest randomness of that. anything can affect periods, even substance loss or putting on weight, stress etc

The subsequent time?

It can interfere with birth control pills. This happen to my niece and she got pregnant. I'm not adage this is the case here.

Help my friend have a problem plz!!?

Actually,I think so. I have a very discouraging sinus infection and was put on Amoxicillin,250 MG capsule. My period hasn't come since. I'm solely 11,not sexually active. Can somebody I don`t know tell me something that would minister to regulate it? (I usually have a regular 30-day cycle.)
