Help guys!!

Today me and my boyfriend had sex. He did not finish in me at all. However after whiping he was still touching me and didn’t wash his hands.

I took a plan B (My way) 1-2 hours after this occurred.

I am 2-3 days before ovulation.

What are the chances of it working ? Or chances of pregnancy?? I’m so scared! I’m not sure if my calendar is accurate since my last period was 5 days late or so. I am planning to get on some sort of birth control. Would an ovulation test help?

Please help ease my mind.
