Not true and why would you just take random birth control pills, especially numerous ones at a time? There is an EMERGENCY contraceptive called plan b that can be purchased at your local pharmacy, that's what you should of taken. Were these pills prescribed to you? Next time you have sex you might wanna think about using a condom even if your under the influence.
I have heard that if you take a certain number of bills (depending on the brand) it should work the same as the morning after pill.

The pill you are looking for is called the day after pill. Regular birth control pills need to be taken daily in order to work.
All In Faith is right, since you took a random number and weren't taking them daily as you were suppose to, your hormones are all out of whack. Which is never any good. I also agree with contacting your obgyn asap!
Birth control pills are used to PREVENT pregnancy, not reverse it. Birth control pills may also take up to two full months to be completly effective due to hormone levels. An emerengy contraceptive is something completely different.
The birth control pills may be effecting your hormone levels. This would cause you to feel tired or dizzy, and could cause anxiety. It is unsafe to swallow a random dose of birth control pills out of nowhere.
I suggest that you contact your obgyn and ask about getting on a daily birth control pill.
