Is it possible I may be ovulating?

Hafsa

I have very irregular cycle. My period was induced by provera and I got auntflow on 1st April and ended on 6th April. I was on clomid and letrozole. I started using opks from the 9th day of cycle and till 22 April I checked but didn’t ovulate. It was showing negative. My opk strips were finished and I couldn’t buy but somehow got it yesterday and I checked. And it showed high. Is it possible I may be ovulating late?
