What is going on

I normally have 28 day cycles. So I ovulate between CD 12 and CD 15. Since Saturday I had brown spotting which turned into light bleeding and it stopped yesterday. My temps or opk’s is nowhere close for ovulation! I’m worried because I’ve never had this before. I was on two anabiotic‘s one for a UTI and another for a STD. I do have a doctor appointment on the 9th which for me is too long to wait. Are these temps normal? Do I chart the light bleeding as a period?
