Follicular scan CD 12

I’m not super experienced with the follicular scans but I am wondering if any of you would be able to give me a little more insight. I took clomid 3-7 and think that I will be ovulating this month due to changes in my cervical mucus.

The ultrasound tech found 3 follicles in ovary. 2 tiny itty bitty ones in each and then both ovaries had 2 follicles around 20mm. The largest one was about 26mm Is this a good sign that I might actually ovulate this month?

Does anyone know how soon you typically ovulate after finding 20mm follicles?
