Nurture app - how to reset dates

Hey, does anyone know how to reset the dates in the nurture app? I had a miscarriage on 14th Jan with another week of bleeding so I changed the status to 'healing from a loss'. Then I thought I was pregnant again and changed the status, turned out to be left over hcg. So I tried to change it back again but it's counting the last 'pregnancy' as a loss instead of the first one. How do I go back to the dates of my proper miscarriage?
