Where did it go?

Amanda • I`m 24 literally married my best friend of almost 10 years May 9th 2015. He has 2 boys 6 and 2 we have been TTC our first baby since March2015. I thought this would be easy as pie, ha I sure was wrong
I think my phone updated, I can't find my bbt chart anymore. It used to be on the bottom bar of the app but not it's a phone. Any idea where the charts are now?
