7 days means 8 pills, so did you take 7 or 8 pills? You’re protected after you take the 8th. If you started within the first 5 days of your natural period you would’ve been protected immediately.
If you used your pills correctly then it doesn’t matter whether you bleed or not. The bleeding you might experience during break weeks is also completely synthetic, it’s not an actual period. Bleeding doesn’t mean much, correct pill usage does.
However I do recommend using condoms until you fully know what you’re doing with your birth control and are confident in its use and educated yourself about it more.
