Cbd and birth control pill failure

Does anyone know if taking cbd oil for anxiety makes the pill less effective? I had sex 6 days after withdrawal bleed started using a condom. I had started taking cbd oil (7mg) the week of placebos and took it for my first two active pills in my second pack. We checked the condom for holes by filling with water but didn’t squeeze it, just filled it up and nothing came out so can I assume that it didn’t break? Please help!

Should I be nervous about pregnancy? This happened 10 days ago. I’m a perfect pill user and take it within 10-20 minutes of 8:30pm.
