Glow doesn't understand my birth control

I'm on the drop provera shot, so I'm not having my period anymore. I keep  deleting the periods that glow sets for me, but it keeps saying I'll have it in a few days. When I get off my BC, it will probably think my cycle is like once a year or something similar. Is there anyway to make glow understand that I'm not having my period, and that it's okay and expected?
