Implantation bleeding or something else?

I have the worst yeast infection I have ever had, which is not bad judging by the things I have heard, but rough for me. I was finally able to get to the store to get some medicine and I realized there was some bright red blood when I inserted the softgel (a lot more info than people generally want, but sorry...details). There wasn't a lot, nothing in the bowl, but on the applicator and TP. I have PCOS and have very irregular periods, basically nonexistent unless I take Provera. I skipped this month because I was traveling, but later in the evening, there was some EWCM and a little of the bright red blood again. My last period was about 5 weeks ago, and I have no physical symptoms, though I have been very emotional the last week, crying over dumb things that normally don't affect me. Had sex during the couple weeks following my last period, but did not test ovulation, and I am generally anovulatory, I think, but I have never been consistent with testing. Should I take a test soon? SO SORRY FOR THE WALL OF TEXT, IT'S A BAD HABIT
