Are bleeding after passing vibin placebo tablets normal?

Hi biore tabketki vibin 1.5 years and last month I forgot to take 2 once I forgot.ezuasc 2 second week And once in 3 weeks. Immediately on the second day both the first and second time after zorirntowanou i took two at a time because it's been 24 hours since omission, I did not take a break between packages because so wrote on the ukotce and since then I have 15 days of small bleeding. It started immediately after taking the second pack without taking a break. Are such bleedings normal and I can last so long and will they pass as I take a 7 day break after the package that I take and everything will return to normal? I am very worried, I will add that I have not had such a situation before I have always taken regularly and have never forgotten to take tablets before. Best regards
