Help with bbt!

Hello, i started temping 2 cycles ago just to see where im at. The first picture is my right ovary's cycle....it clearly looks biphasic and like i ovulated normally. My hubby and i are taking a break from trying after 4 failed iuis so i didnt do any opts. Now look at the second picture from my left ovary's month....it looks like i didnt ovulate right? All of these were taking around the same time everyday. Any help is appreciated.
