If I didn’t use OPK I would think I ovulated around cd 8/9 which is insanely early, but I’m thinking around CD 15 now? I am using the Ava bracelet so temp timing is not an issue. I normally ovulate the day of or after OPK, but on CD 15 I randomly took one that was negative but far darker than it would be for me after O, so maybe I had a second LH surge on cd 14 and ovulated late? Any feedback would be helpful!
