Nurture App HELP PLEASE

Betty

Apologies if this is the wrong place but can't find anywhere to ask!

I downloaded <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">Nurture</a> as I got bfp (:D) and now it says I'm "not yet pregnant". Think it may have taken the first day of last period as today (Dec 11th) rather than Nov 11th when it was...

Someone please tell me how to fix?

I've uninstalled and reinstalled but it doesn't ask the question any more :(
