Plan b late

So I had protected sex 3 days after my ovulation week. The condom broke and he ejaculated inside of me. Within like 7 minutes he ran to the store and got me a plan b. My period was supposed to come on 4 days ago but I’ve had nothing. I took a pregnancy test 2 days ago and it was negative. My boobs hurt a little and I have a slight yeast infection . What is going on with me??

I also have my first gynecologist appointment tomorrow morning but I’m slightly scared cuz my mom will be present. I will like privacy in the room

But I know how she is🤦🏾‍♀️.

Do you think I’m okay?
