I found out a week ago i was expecting, So I'm new to this app as of today.. I've typed in my first day of last period and it's saying I'm 5.5 weeks pregnant. However the app I've been using is called 'flo it's an app that you use to track your periods, obviously I've found out I was pregnant after 8 tests:) so I clicked the button 'pregnant to stop my period predict chart and it does the job for me (when I conceived), that app says I'm 7 weeks pregnant I'm popping out already and these 2 apps have just confused me now! Helpp!
