Symptoms and period is due August 3rd

Dyani
So for about 4 days now my boobs have been super sore taking off my bra hurts(even a sports bra) I accidentally bump them or touch them they hurt, I've been lightheaded(so bad I bump into the wall), lots of different kinds of discharge (no smell) nausea and vomiting, my whole lower back hurts, I've been having on and off headaches for about 2 weeks now, and I have a pain in my stomach that's moving from one place to the other. I'm going to the doctors on Monday should I take a test before that? Or just wait? Or does anyone have advice?
