About 4 days late

And about 4 days ago I started getting super dizzy and lightheaded. I've been having cramping almost every day but haven't bled yet. I've been stressed to all hell lately as well and haven't really been eating because of it. But October was a very active month sexually, and because I've been slacking on getting birth control, my bf has just been pulling out. So now I'm stressing about that on top of my other stress which doesn't help at all... can my period just come already? I'm not mentally or financially stable enough to add this to the table rn...
