Low fertility days

Chanel🎀 • 20 years old🎉 expecting baby #1 due july 11th 🚼 engaged 💍👰🏾
So this is my 2nd month using clear blue advance ovulation test. And last month on my fertile week i was getting high fertility but never a peak day and now this month im getting low fertility. Am i not ovulating right ? I only have 3 more days left in my fertile window.
