I am on Marvelon 28, is it normal to get your period on the first day of the active pills?

I have been on Marvelon 28's for 3 months I was on Alesse 28's before that. Ever since I've been on the Marvelon's my periods have been arriving the same day I start the White Pills (active pills). All while I was on the Alesse I would get my period on the 4th or fifth green pill (sugar pill). I'm kind of worried about this, should I be worried?

When you switch pill brands, it's not unusual to see changes like this.

It's perfectly normal to get your period as you begin to take the active pills. As long as you took your pills as directed (at the same time each day, no antibiotics, etc.) you are still protected against pregnancy, no matter when you get your period.

It's not unusual for your periods to be lighter, earlier, later or even less frequent on one brand of pills compared to another. Every woman also responds differently.

Keep taking your pills as indicated. If the change in cycle really bothers you, talk to your doctor about going back to the Alesse, or trying another brand entirely.

Hope this helps
