Changing my dates?!

Vanessa

I don’t understand why is changing my prediction dates (ovulation and periods) my period was supposed to come on the 9th and because I’m late is showing me a waaaay far different date? It doesn’t even go with my cycle length anymore. I’m starting to get frustrated plus it doesn’t say anything about my symptoms or if I should take a test.... it’s not giving me anything good to keep in this app.
