Solid smiley next steps

Hi there, 

I started testing on my day 8th, had to blank circles following by flashy smiley and then the steady one day 11

I waited for 48h, had sex two days in a row during that time.

Once the smiley was gone I continued to test my self.

yesterday was a blank circle and today steady smiley again - day 16

Am I ovulating still? Is it recommended to continue to test yourself after 48h of solid smiley?
