Plan B experiences or knowledge?

I just took the pill for the first time and I’ve read all of the scary things and not so scary things about it on the internet. I took the pill probably within six hours of having sex, and I’m supposed to get my period in a couple days anyway but the condom broke and the two of us nearly had a full blown panic attack. I know if my period is late I’m going to shit a brick, though I know that’s one of the side effects...

I just want to know some stories and maybe what to expect based on some of your experiences. Thank you 😊
