Re: Switched from Estrostep to Cyclessa, please read....
Yes, you did that correctly. You should be just fine.
Whenever you switch from one pill to the next, it's a good idea to complete the pack you're taking, allow for the week of placebos, and then begin your new pack of different pills on that following Sunday (or whatever day other people start).
So you were exactly right the way you did it. No worries.
