Flo app help..?

Ashley • 25🧸Mommy to 1. Pregnant with baby #2! 9 months TTC🍼

Can someone explain to me why I have my fertile days SO close after my period? I have a regular 28 day cycle. Sometimes 26 sometimes 29. Mostly 28. Soooo why do I have this many fertile days? I’m so confused because Glow is different and says I’ll ovulate about a week after my period. I’m trying to track my ovulation but damn lmao
