At the moment, there isn't a way to log a miscarriage in Glow, although this is something we’re working to improve. The app will “read” the gap in period data as a long cycle, which may skew your cycle averages in the Genius section. However, this long cycle does not impact your cycle predictions, because the app excludes any such outliers from its predictions. If your predicted cycle length is not what you’re expecting now, reach out to our Customer Support Team at firstname.lastname@example.org and they can get your predictions back on track! If the predictions seem spot on, we would suggest not changing the data.
If you’re looking for a Community in which to learn about others’ experiences with miscarriage and meet other women, you can download Nurture, our pregnancy tracker app, and choose the Healing from loss status. That will provide you with a unique Nurture experience designed to ease you through this difficult time.
