How to add new pregnancy to nurture app?

I’ve selected that I want to track my pregnancy in the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>, and it transferred me over to the <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">Nurture</a> app. However, it jus has the info for my previous pregnancy and so the calendar just tells me how many weeks old my baby is now. How do I add a new pregnancy and have it track that instead??
