Help?

So y’all for the past three days I’ve been kinda wilding, I’ve had sex three times this week and it’s my fertile window according to eve. The first time i had se the condom broke🤦🏽‍♀️but he didn’t nut yet. The second time it was unprotected and but he pulled out and the third time i was “ovulating” and it was unprotected but this time after he came he wiped off the semen and put it back in. Long story short I wanna know should I go buh a Plan B? Or should I be okay?
