Plan B and ovulation timing

Y’ALL! I need some help.

Two nights ago, my man and I had unprotected sex- this is the first time I’ve ever let him finish inside of me. That being said, I had already passed my ovulation period and I should be starting my period in about two days.

I took Plan B the day after we had sex, but I know that plan B just delays ovulation so... I’m freaking out a little!

I have really bad anxiety, so this could all just be my brain making me go crazy and overthink everything.. thoughts?
