did i take plan b too early???

m

So a few weeks ago I ordered option 2(i’m referring to it as plan b)on amazon just as a back up to have in my medicine cabinet because i realized i didn’t have any emergency contraceptive. yeah it wasn’t the best idea but it seemed legit considering in was 4.7 stars with 7k+ reviews. i am on birth control and take it pretty religiously. my alarm is set for 9pm which is usually the time i take it but i make sure to take it anywhere from 8:30-9:30pm no excuses (sometimes life gets in the way). anyway on the 25th my bf came in me and you know the phrase “the sooner you take it the better” so i took it less than 30 minutes after the incident. it is now the 29th and i’m nauseous, bloated and have slight lower abdomen pain. of the few other times i’ve taken plan b i had sore breasts, nauseous and bloating all about 24 hours after taking it for about three days. i’ve read that you should wait 30min to and hour before taking plan b. Has anyone bought option 2 from ‘good sense store’ on amazon, is it legit? did i take plan b too early? if option 2 wasn’t real, should i be protected by my birth control? is how i take it considered perfect use? sorry for so many questions this is the first time someone came in me (it was consensual but it was also the heat of the moment) and i’m now nervous hahaha thanks.
