Second time using blue clear ovulation tester

I got a blinking smile face 🤩today I took the test at 8:15 am this morning I’m on cd 11 I ovulate in 4 days 🤪yesterday I took the test in the evening and got a blank circles so I think I have to take it in the morning 🌞not just anytime I’m still learning but I’m really hoping this month is our month for our rainbow baby 👶🏾🍼💙💕🌈 I really think I’m starting to like this ovulation test it help me have some time of peace and mind 🌼 because after the miscarriage I thought I wasn’t ovulating because we been trying for 11 months now so I hope this is all going right for me
