Yuzpe method for unprotected Sex after 23 days of birthcontrol

I was on Trust Pink Pill and stopped using it around Aug 18 or smth. I had unprotected sex on September 9 and he came in me. Did the yuzpe method and took 4 pills for the first dose and 5 for the second dose. I am 109kg but using daily birth control was effective for me.

I am worried since I saw that the yuzpe method is not that effective during ovulation but I do not know when my ovulation occurred since I stopped talking pills. And I am also a bit concerned about the effectiveness of the method considering my weight. Has anyone every experienced this before? Huhuhuhu
