I had sex for the first time on 12th of this month. The next day I took emergency contraceptive pills. If I am not mistaken I am supposed to get my period soon after the pills. We had unprotected sex again after 3 days of that. Next day also. After that am on 21 day pills. I am confused about this whole pills thing. I haven't got my period yet. So scared as well.

Well of course the normal birth control pills are not effective till about 30 days after starting them, so they have no effect at this point.

I do hope you did not take TWO morning after pills, they are not for regular use just emergency usage and taking too many close together run the risk of worst side effects.

As you know the morning after pill is not 100 percent effective and often you may not even get a period for a month or more as a side effect.

There is nothing you can do at this point, expect stop having unprotected sex, till you have been on birth control pills at least a fulll month.

** how did you start taking birth control pills, if you did not have your period, are you not suppose to start them after your period?

If you don't want a child then why engage in unprotected sex? Most birth control medication is by prescription, so you should consult YOUR OB/Gyn to explain to you how to use them properly.
