Calendar-- I'm SO confused. Please help!

Marissa

So I have a couple apps to track my ovulation and period but I'm BEYOND confused as to why they all say different due dates for both ovulation and period. Especially when they all have the same data as to when my period started and ended over the past 6 months at least...

I don't know if it's just me or what but it confuses the shit out of me. 🙃

Thank you in advance for your comments/answers about why this is happening! ❤️
