When did I ovulate? Still bfn and no af

Samantha

Hey ladies, has anyone run into a similar experience where they had what they thought was a peak, only to peak again a week later? I’m trying to figure out when I actually ovulated. I had my first peak 11/29 and then another 12/5. Based on my bbt I think the first peak may have been accurate since I see a rise after but my actual darker peak opk was 12/5. I’ve taken a few tests and bfn so far but maybe too early if I ovulated late?
