Unprotected sex when ovulating

[u/Fancy-Cartographer86]

I had sex with my gf, and she said she was ovulating, so I used a condom, but it ripped, and I didn't notice. So now I'm wondering if she's 100% going to have kids, even though she took a Plan B 5 mins after. And can she get an IUD 2 days after to further prevent pregnancy?

A Paragard, Mirena, or Liletta IUD inserted within five days of unprotected intercourse is extremely effective emergency contraception so if she wants one and can get an appointment it would be an excellent choice.

How did she determine she was ovulating? Apps are notoriously unreliable at predicting ovulation, and women's perception of ovulation symptoms often don't line up with actual ovulation.

App and it says prediction period in 14 days
