I took the contraceptive Tâmisa 20 2 years ago ...

Hello, I took the contraceptive Thames 20 2 years ago, the most I forgot was 1 day but this time it was different. I finished taking the last pill, I menstruated on Thursday and did not start taking it until today (Monday). What do I do? Do I take back and finish all the pills? Do I take back and eliminate the days I should have taken? Am I at risk for pregnancy if I have sex without a condom? Thank you!
Expert answer:

Start taking today as normal and use condoms during the first 15 days of that month.
