Before you started taking Drovelis tablets, the periods were regular and lasted 3-4 days, now more than a week - will there be any change after 3 blisters?

Drovelis, the period lasts 2 weeks
Good morning, I'm just finishing taking 2 blister pills drovelis and my periods look like in the picture below. Should I go to the doctor or wait to see if there will be a change on the 3rd blister and the period will be shorter? Before starting to take the pills, the periods were regular and lasted 3-4 days. This is my first such form of contraception, apart from condoms, of course.
