Confused about cycle

Heaven

So I have a semi irregular period and I just started <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> (via saliva ferning) about a month ago.

Do you think Glow changed my expected period date because I manually added ovulation and it just doesn’t know how long my luteal phase is or is my period really expected tomorrow? 32 days just seems so short to me.
