No af symptoms & no pregnancy symptoms

D.

Soooo my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says I should start my period today & my other apps say I should of started my period yesterday. I don’t have any af symptoms. But not any pregnancy symptoms. Except maybe nausea and heartburn . & I ate everything in sight last week . My boobs feel heavier but a little less sore today. I normally have like diarrhea leading up to my period. But yesterday and the day before I had some minor aches in my ovaries but it switches sides. But idk I don’t consider these symptoms because they could be anything.
