Heart attack at 23?

I know, I will be going to a doctor but i just wanted people’s opinions. So lately i’ve been getting a weird overwhelming feelings in my chest like i need to take a deep breathing. I’ve also been experiencing teeth pain and heart pain and a lot of indigestion. I did take Plan B two weeks ago and I fainted two days ago and when i fainted, they checked my BP and it was high, not low. Has anyone had similar symptoms to plan b? Or do you think it’s not related at all?
