Ok so I been on glow since May 18 TTC I have been logging everyday all month it said my cycle suppose to come on the 17,18, and 19 when the 17th came it asked me if I had my cycle I said no so here's the question why when I said I didn't have my cycle it changed my period days to the 20,21,22? To me I'm thinking hey I'm a day late for my cycle that's a good thing but now I'm confused and it's like the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> was unsure of my cycle the whole time. Anybody else had this happen to them?
