Hi everyone! i am new here but this is a great community!! i have been using glow since January and it has been helpful but now im confused!!! my first cycle was 28 days my second 23 days and according to the app the next one 29 days. my periode is due this Tuesday today is Saturday but if i was to go by last month (23 days) i am already late and can take a test but if the app is right and its 29 days im too early to take it. I don't understand why its 29 days. also the fertile window was always 5 days according to the app this month i took an ovulation test and didn't ovulate till day 7 so now the app has made every month 7 days. could that be the reason this months cycle has been calculated 29 days? thank you for any reply!
