Should I or should I not test? A little TMI

Ok, so last Friday I started feeling nauseous and lower pelvic pains. Some sharper than others. Same continued on Saturday and then Sunday got bright red blood in the am. When I changed tampon half way through the day there was like not much blood and same when I went to bed. Still nauseous. On Monday, I was nauseous all day and had pelvic pain. I did pass a decent size clot but not much blood other than that. Tuesday a little dark but only when wiping after the bathroom. I am still nauseous, which gets better after I eat something, still have lower pelvic pain as well as headaches. What do you think ladies?

Cramps are typical for me when am never nauseous with af.
