Different apps different FW

Melody

I’m tracking fertility against a few different apps but they’re giving me different fertile windows..

I’ve had negative OPK since CD5, I had ewcm on CD10 and today CD14 a lot of af type cramping and heaviness but minimal cm and quite light and milky.. I usually have a 25 day cycle..

This app says I should ovulate today but cm and neg OPK’s makes me think not..another app says I should’ve ovulated on cd9... what do I follow??

Whaaattt??!! 🤷🏽‍♀️🤷🏽‍♀️🤷🏽‍♀️
