Hey Girls!
Quick question...what's your regular ovulation length? 
(I was told  y Glow I was ovulating so I did my strips and lines were decent color, took another one and was dark...however this was after 5days of ovulating before. And because I am bored out of my mind while my husband hunts I just took one now to see what it do and here is the result. I'm supposed to get my period the 30th. But holy burnt pickles did I just ovulate that much?! Hahaha)
