... stressing about this for the longest. My period was supposed to start in 3 days and I’m scared that it won’t?
It depends where you were in your menstrual cycle when you used Plan B.
Plan B is not as reliable as regular hormonal birth control. It's simply worth a try in an emergency.
If you were fertile, then Plan B may not be the best form of emergency contraception. It works by delaying your ovulation until the sperm leaves your body. If you're already ovulating then it can't do that. In that situation you may be better using one of the other methods of emergency contraception; such as the other emergency pill called Ella (Ulipristal Acetate), as it's proven to work in more ways.
Some think Plan B works in other ways, & indeed it might, but the Manufacturer does not claim that. They say it's possible, but don't say it does, as it has not been proven. You can see that on the Manufacturer's website.
So it depends on if you were fertile.
Plan B is a huge dose of artificial hormone for your body to deal with. It's very common not to get your next period on time. You can get any hormonal symptoms that you'd get with a period or pregnancy, or other hormonal change in the body.
