Do you guys think I likely ovulated on CD18?

I had to temp about an hour earlier than usual this morning and about 30minutes early yesterday. I typically temp at 6am but I’ve been waking up earlier lately - yesterday at 5:30am and today at 5am needing to pee. Since I know I won’t get enough rest between then and my usual temp time, I’ve just been taking it then. I’m not sure how much of a difference that would make in my temps
