Hi there -
If you are having problems with the app (besides the "show more posts" not working), can you tap on Settings in the app, then Support, then type an explanation of the problem, and send us an email? When it asks to send data, choose yes. This sends our app support team an email, and they can check it out.
The calendar should be accurate, and shouldn't be changing like you describe.
Thanks, and we apologize for the inconvenience.
Emily
You can not base anything off the calender its not acurate u need to by ovulation tests and I suggest the ones with smiley faces then add your own info and do this a couple months have sex a cpl days before ovulation becomes positive and then day of day after
