Ovulating?

So I have been charting my ovulation since my HSG on the 4th of this month, but since I'm so irregular, I never really know when I actually ovulate. All of my lines have been faint up until around the 23rd when I was hit with this.

And then again on the 24th, I was hit with these lines.

I want to say it was positive, because on the 25th and thereafter, it was back to being light again. What's the chance I ovulated somewhere around Christmas?

I did get to BD on the 22nd, 24th, and 26th so I'm hoping that was enough to land me my rainbow bean if I did.
