Can I be pregnant if I had intercourse without a condom during a 7-day bleeding break at Atywia Daily?

Hello. I have a question about tablets atywia Daily. I have been taking them regularly for several months, I do not skip any or use any thing that could reduce the effectiveness of contraception. You can say that I got withdrawal bleeding during a 7-day book break with 3 tablets of placebo, while I made love to my boyfriend during this break, and more so on the day when in the evening I took 1 tablet proper after the aforementioned break. Dziaiaj morning or Tuesday (4 days after intercourse) began to hurt my lower abdomen. Maybe I'm over-sensitive about this, but I'm afraid of a pregnancy that I'm not ready for, should I be afraid of it in that case? Can the partner end up in the sever? Is such a pain in the lower abdomen in such a short time a symptom of pregnancy? What is the real risk of pregnancy if you take contraception correctly, without reducing its effectiveness through diarrhea, vomiting or medication.
