I had unprotected sex in my ovulation day and i took plan b 5 min after the intercourse can i still get pregnant?

Possible, unlikely: It's still possible but very unlikely for you to become pregnant with proper use of Plan B. A fertile woman who has unprotected intercourse around the time of ovulation has on average an 8% chance of pregnancy. With Plan B onestep used correctly, that chance is reduced to just under 1%. In theory, this risk is reduced further the sooner the therapy is taken after intercourse.

Unlikely: Plan B One Step can reduce chance of pregnancy by up to 95% when used within 24 hours.
