How do I start using Slinda if I removed a Kyleen insole 2 months ago?

If you started using contraception as prescribed on the first day of menstrual bleeding, you do not need additional mechanical contraception. Almost 2 months have passed between 4.11 and 1.01, so we consider that "you have not used hormonal contraception before (in the previous month)" and follow the above recommendations. Perhaps the doctor decided that "prudent, always insured" and simply preferred to recommend additional security. According to the mechanism of action of contraception, this is not necessary if it was actually 1 day of menstruation, and not possible spotting occurring since the discontinuation of the IUD. On the site we have a lot of useful articles about contraception: https://www.gdziepolek.pl/artykuly/antykoncepcja-hormonalna https://www.gdziepolek.pl/artykuly/jak-prawidlowo-stosowac-antykoncepcje
