Test or no?!

So I'm officially a week late on period! I don't know if I'm pregnant, have had bleeding when i having sex a week or a week an half ago, stopped later that day. Mild cramping where you get period cramps, nausea, headaches, dizziness and some heartburn. But only ones that struck me was the bleeding and cramping with absolutely no period days to a week later! Should I test tomorrow morning?! Idk if I should or wait?! Poll please and give me some advice as what to do? I'll tell y'all anything you need to know to help me out! Thanks!
