Birth Control🙄

Okay so I'm taking birth control and the time I take it varies from 11-12 MIDNIGHT, I usually forget and when I do I breakthrough bleed and I forget ALOT so I've bled for atleast 3 weeks straight which can't be good...I need to change my time and tomorrow I start a new pack so I'm wondering what time you guys suggest. It is summer now but starting August I will be in school from 8-3 so I have no idea what to do! Any suggestions, any tips?
