🆘 Birth Control 🆘

I’ve been using my birth control (Alesse 28-Day) for about 7 months now. I used to have very heavy periods but that got cut down to light/medium for 4 days after taking BC. This last “period”, I was extremely light. There was a lot of dried up blood/brown discharge instead and it wasn’t like a real “flow” more like spotting. I was bleeding for a few hours so I could say it was about a light medium and that was it...

Is this normal? has anyone ever been this “light” while on this BC.

I do take my BC at the same time every single day religiously, never missed.
