I’ve been using clearblue connected (Bluetooth app) for several months and this cycle I had only about 4 test sticks left, I got high fertility on the last 2 days which is cycle day 9 & 10, they didn’t have anymore clearblue connected at my local store so I purchased the clearblue advanced instead thinking it would just pick up right where I left off for cycle day 11, when I tested I got low fertility? I used the new holder that CB advanced came with because i was advised that test sticks are for the specific holder. Has anyone experienced this?
