Since when am I protected from pregnancy, if I finished taking an antibiotic on 3 tablets of Atywia?

Good morning. I was prescribed atywia as the first birth control pills, the first tablet I took on the first day of menstruation, today will be the 9th day of taking tablets at a fixed time. However, a week before menstruation, until the third day of taking birth control pills, I took an antibiotic, which in the leaflet contains information on the weakening of the effects of hormonal contraception. Is I already protected from pregnancy after a week without an antibiotic and 9 days of taking the tablets? Best regards
