Did I ovulate this month?

Hi ladies, can you please take a look at my bbt chart and let me know whether you think I ovulated? The chart doesn't make any sense to me. The temp increase isn't sustained and dropped in one day. I had ewcm for one day right around the time the app predicted ovulation, but I have watery (a lot!) cm after my alleged ovulation a couple days ago. I'm now not sure whether I actually ovulated or not...Any input is greatly appreciated!
