Multiple BBT Spikes & Dips

Le

Hello, I’m new to charting and life off birth control. I stopped the pill in August, no withdrawal bleed and had my first period Sept. 19 (47 day cycle). I’m thinking I did not ovulate yet and my body is still trying to balance. Can anyone confirm? I have been taking temps at the same time every morning before getting up and have not been drinking alcohol. Any insight would be greatly appreciated. Thank you!
