Please help - switching birth control pills.

So I’ve been on aubra for 13 months and I’ve been prescribed chateal. Is okay to do placebos and start the new ones like as I did with aubra? My boyfriend and I don’t use protection (yes both tested and both clean) so is there a chance I could get pregnant if switching at the same pace or should I do it somehow different, I honestly don’t know and please need insight
