Having odd symptoms TMI

Hey there ladies so I’m 8 DPO... I recognized yesterday that I’m getting a odd breakout on my neck which I’ve NEVER had, I also have a small pimple/cyst between my breast it’s red but not to painful.... only my right nipple stings, and I’ve noticed some thick discharge. I’ve been late before, and never had any of these symptoms. You think I should try to test 9 DPO, would anything even show faint by then?
