M a girl of about 25.

I had an unprotected intercourse on 11.06.2012, after which I took a contraceptive (ipill). On 15.06.2012 she experienced a period like fall and this continued on the next day. Third day my fal stopped and till date I have not experienced my periods.

I regular period for the month occurred on 02.06.2012. Is there a reason to worry on this ?

Kindly advise.

One sentence says I, the other says "she" so who is who here and what is going on.

But OK, you had sex, you did not use protection and used the morning after pill.

You can be pregnant, since even the morning after pill is not 100 percent effective.

Most likely you are not, the morning after pill can cause these side effects, did you not read the material that came with the pill. It can have many side effects some more serious than others
