Test sticks broken for two times

I’m using Clearblue Digital ovulation test (purple cap with 20 tests). I’ve been tracking my ovulation for about 6 months and everything was fine until recently.

First box (20 tests), after 12 tests are used, the test result has become a blinking smile for 5 straight days, which I believe it’s not possible. As a result, I purchased the second box (20 tests). I then tested the new test stick and old test stick as a comparison. It turned out the old test stick was broken.

So I’ve been using the second box until yesterday! The result of blinking smile has come out for 3 straight days AGAIN!! I purchased the THIRD box. I then tested both old stick and new stick today. Not surprising, the old stick was broken AGAIN!!

It was so frustrating that the stick keeps breaking and it makes me even wondered whether the test result was ever accurate.

Hi Claire, and thanks for contacting us about your results with Clearblue Advanced Digital Ovulation Tests.  It's important to know that High Fertility results (flashing smiley) won't necessarily always be shown for two days.  Hormone levels and cycle length vary from one woman to the next, so your High Fertility results are personal and reflect your unique hormone changes.  It's normal for some women to see more than two High Fertility days in all or some of their cycles.

For some background info, this test tracks the changes in 2 hormones:  estrogen and LH.  If the necessary changes in estrogen are detected, the test will display High Fertility.  Once High Fertility has been detected, your result will continue to be High Fertility until an LH surge is detected, at which time Peak Fertility (solid smiley) will be displayed continuously for 48 hours.

Having said that, it's important to use the same digital holder for an entire cycle of testing.  If you switch holders or introduce a second holder in the middle of your cycle, you may see unexpected results with the new holder.  This is because the first test in your cycle is designed to take a baseline reading.  

I hope this is helpful.  Feel free to let me know if you have other questions!
