Plan B: please help! I’m scared to be pregnant!

I had unprotected sex on January 11 (He pulled out). We always used condoms each time but this time we didn’t. So I took Plan B on the 13th (yeah I know I should’ve taken it sooner). I took it within 72 hours, as the directions said. I’m not sure if I miscalculated the timing or not. According to Glow, it said I started ovulating on the 7th, but the 12th was the actual ovulation day?? I’m confused.

Based on this picture, will I most likely become pregnant even though I tried to take plan B as soon as possible? My period is expected to start next week on the 26th. I’m really really scared of becoming pregnant. What should I do? Do I worry about being pregnant on this period or the next period? When can

I test for pregnancy?

Thanks for any feedback!
