Pregnancy chances

ka

So I was wondering what my chances of being pregnant were.

Is had sex 4-7 times a week my entire cycle and just coming off birth control we’ve been tracking my period like I was trying to become pregnant to avoid peak days when we had sex. We’ve goofed up though and had sex on days 2-3 days before my ovulation unprotected completely meaning not even a pull out. Is it too late for a plan b or are we ok?
