is ovulation like this possible?

Im already like a week & a half late with negative test. Rn i feel like im ovulating & my cm looks the fertile kind. Last month i didn't feel like i ovulated & i usually ALWAYS know when my fertile day is. My ovulation was supposed to be like about 2 or 3 weeks ago now. Is it possible that i can be ovulating until right now?! Or should i just take another pregnancy test to be sure?? I think by now that test should be accurate since im late by kinda a lot right?
