I am 22 years old and had unprotected sex. I even had I pill after that. I was supposed to get my periods by 22 of this month but I have not got them. I am scared if I am pregnant. Is there any medicine or tablet by which I can get rid of pregnancy because I do not want to have a baby now.
Please advice

When did you have sex and when did you take the ipill?

The ipill can affect your period. Three days is a 'late' period and could be caused by stress (or several other factors) as well as the ipill.

I suggest visiting your doctor for a check up and to discuss pregnancy and birth control options.

First you need to find out if you are pregnant. So you need to wait until 2 weeks after your due date and start taking a HPT. If you are pregnant, then you could discuss ways to abort with your physician. There are ways to medically abort at this early stage.

But, if you took an iPill properly, its unlikely you are pregnant. The iPill and stress could affect your period. And, if pregnancy scares you at this time, then you need to keep your logs closed as no form of birth control is 100%.
