Using the app after miscarriage

St

Hello, my last period was in March. I got pregnant but had a miscarriage two weeks ago. Is there a way to indicate this in the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a>? It is currently showing that I have irregular periods because of the gap. Is there a different app I should be using?
