Add a pregnancy?

I keep logging positive HPTs, but I am not given the option to add a pregnancy and use the <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a> app like I did with my last pregnancy. When I log into <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a>, it brings up my old pregnancy, even though I entered the birth date and everything.

How do I get glow to know I am pregnant?
