Does drinking beer after taking the contraceptive pill and intercourse lead to pregnancy?

Good morning. I have a confirmed pcos. Since May I have been taking diane-35 and Androcur. From 2 cycles I have a break with androcur. On October 19 this year, there was withdrawal bleeding on the 4th day of the break. From October 23 this year I started another blister. Then I made love to a boyfriend without protection ended in me. At 6 p.m. I took the pill. And the next day I also loved myself without protection the same and took a pill. Then about 4-5 hours after that I drank a beer. Could fertilization have occurred? I have been taking pills for a long time and I have never missed any. And I'm very afraid of it because I don't want to... these 2 days were the first two days of tablets from the new blister I take at a fixed time at 6 p.m. Sometimes a few minutes earlier or later. Please reply. It seems to me that the protection has been preserved. But please odp. To exclude pregnancy.
