Heavy withdrawal bleed on Pill free week

Isha

So I just finished my first ever pack of Combination BC pill (I use the 21/7 method) and currently on my 7 day break week and on period. I got my period like 3 days later and it’s kinda been heavier than my usual period (I’m a light bleeder). I didn’t feel any cramps on my 1st day so that was a plus for me but is the heavier period normal?? bcoz all I’ve ever read anywhere is that BC makes your period lighter!
