Ovulation and plan b

My boyfriend and I had sex three days ago and the condom broke, so he got plan b the next day and I took it that night. I took two ovulation test today and they were both positive. Why is this? Am I ovulating? Did the plan b not work? We also had sex again this morning and that condom broke.. (yes we used a different brand and it still broke) and we decided to not do anything about it this time because I already took plan b 2days ago.

The first day the condom broke my period tracking calendar said I had three days before ovulation which would have been today.. and I’m getting a positive ovulation test, did the plan b not work?
