CD20 - test line darker than control line

Alexis

I forgot to test and randomly took an a test on CD 20 and got this! Is it positive? Is it possible I ovulated on CD 18 or 19 and still have the surge on CD 20? We BD CD 15, 18, 19, 20 and 21 and we’ll BD again in a few hours. Did we cover our bases? I finally had stretchy CM from CD18 on.
