Has anyone else had problems with this app telling you your menstrual was supposed to start but never start?? Take a Pregnancy test it comes out to be negative but your menstrual was supposed to start 10 days now 12 days ago..And you get so excited for nothing because it was all wrong on when ur menstrual was supposed to start but u think it's was right and you're taking all kind of pregnancies test wasting money...... I been using this app for over a year😡😡 I was hoping that this app was going get better and start to work after a year of using it...I'm thinking about just deleting it does anyone know of any apps that really work and I'm paying for it every month for it to be wrong do not waste your money on upgrading hope this was helpful baby dust all👶🏼👶🏼👶🏼👶🏼 Please do not leave negative comments thank you
