Ovulation...

So I had a position opk on the 12th around 9 pm.

I started progesterone immediately after, and the next morning it was positive again. However, four hours later around noon on the 13th, it was negative.

Normally when I ovulate they’re positive for a couple of days, is this 12 hours normal?
