Okay so I started using the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> in January. So I'm a new user. Anyway, towards the end of the month it showed me my ovulation days but when I took my ovulation tests the days on the calendar changed 😐. Is that normal? I'm TTC and when I see the ovulation dates change its very confusing. Does this happen to anyone else?
