I'm on birth control....im on 7 break bills......i do not want my period for 7 days. can i take my active bill on the 4th day to shorten it?

24 days active: Women on 21 day active pill birth control pills, who want to shorten their menses can try to extend the 21 days active pills to 24 days by adding three days of pills from the next cycle to the ongoing cycle. They will then take 4 break pills instead of seven and start a new pack.

Yes: You can start the next pack on day 4 (or earlier) to shorten your period. Best wishes!
