Birth control/ pregnant ?

So I recently went on the pill and I know that you’re not covered the first 7 days. My boyfriend and I had sex on day 8 and came inside me so I took plan b as a precaution. We had sex last night (day 10 on bc) and he came inside me again. I also checked and there’s a high risk of pregnancy. I don’t want to take plan b again bc it would be the third one in less than a month. Am I good? Or am I probably gonna get pregnant?
