Is it normal for me to have spotting before the 7-day break that disappears during the break?

Good morning, I have been using the Ginoring disc for half a year and I noticed such a dependence that a week before removing the disc I start spotting which becomes stronger every day, and when I take out the disc for a 7-day break spotting in about 3 days passes me is it normal? I would like to add that the disc is used regularly and watches over the times of insertion and removal of it so that contraception is preserved.
