Ok... at the beginning of last month my period came 3 days early :(. Im usually a 26 or 27 dayer. So glow was predicting I would get my period yesterday since my last cycle was 25 days. I selected that my period was late and glow says tomorrow for af. Tomorrow I will take my erpt if af doesn't show! Trying not to get too excited but I just wanted to share. I have nooo symptoms so I'm just keeping my fingers crossed.
