What is the risk of pregnancy? Is it worth taking a tablet the day after? Can I be pregnant?

Hello! I have been using Belara contraceptive pills for 8 months. I feel good after them and have never had side effects. I got my period on 19.08 and it ended on 24.08. I had intercourse two days before menstruation (17.08 and 18.08), my partner ended up in me every time, then I had intercourse on the third day of withdrawal bleeding also with ejaculation inside. The last full intercourse took place on 26.08. On the 14th day of the cycle, we used the intermittent method. After months I had symptoms of ovulation, i.e. I had cramps and lumbar pain. Symptoms began a few days after menstruation and lasted until about the 15th day of the cycle. What do I know about Belara tablets inhibit ovoulation and it completely does not occur. I would like to add that I did not take other drugs or preparations that mask the effects of tablets. What is the risk of pregnancy? Is it worth taking a tablet the day after? Can I be pregnant?
