BBT - help read

Lynn • Started ttc in Feb 2016. Started at a fertility clinic in 01/2017! Found out I was pregnant in June 2017! Due 02/2018
So I just found out 6 weeks ago that my thyroid is off. I found this out because I had an 81-day cycle. My levels are now very close to normal. Can someone look at this chart for me? I'm pretty sure this means that I didn't ovulate at all. But would like some help. :). Thanks!
