AF MIA for “2 months”

Anna

So i started trying in July. Had just gotten off bc. In July i had light spotting when my AF was supposed to come but all tests negative. August i thought i ovulated. We tried again AF still MIA and it’s CD 41. 11 days past my missed period. I tested shortly after 4 days after my missed period and they were all negative. Should i test again before starting my ovulation testing again? Or should I see a doctor soon?
