? FF wrong on ovulation?

Hi this is my chart this month so far after missed miscarriage with D&E as CD1. CD 22 but I was out of town for a funeral and drank a lot with my family so it would have been inaccurate anyways. I feel like I probably ovulated CD 22 and my body just tried to ovulate earlier?? If you look at my previous charts my temp notoriously has a big dip before ovulation. The 2 previous months were chemical pregnancies FYI 🤦‍♀️. Also still have superrrr faint pregnancy tests but I’ve since heard some people ovulate when it does reach super low levels? Was not expecting to ovulate because I still had very faint positive tests 😳. And I know I need to be better about time of temps, I was just slacking this month because we weren’t trying. My husband was just into sexy time
