Ovulation issue

JJ*

Hi all,

I have 3 apps that track ovulation (obsession i know) all 3 have different days 1 says ( Flo )6 Dpo , 2 says(Ovia) 12 Dpo , 3 says (Glow) 15 Dpo.i have tested about 3 days ago and it was negative.

Should I test or wait I have been feeling nausues,cramping sometimes, funny stomach , peeing often , headaches and moody.

My periode should have been here 1 day ago
