So I been testing high fertility for like 4 days now. Been using clear blue with the smile faces. Well I ran out went back to the store and they had the clear blue but was a bit different. So I got them. Well I been testing with both now just to see. I checked last night one had solid smilie and the other was flashing. This morning I tested one is flashing one is not. I'm so confused. Can anyone help? This is my first month actually tracking. We been ttc for 5 months now!
