Not detecting the surge
Hi there! My wife has been using clearblue for two months/cycles now. She followed the instructions on the first cycle, but never showed a surge and had a period. To ensure she didn't miss it again, she tested it everyday from the end of that period to her next, with clearblue never detecting a surge. We're going to be trying for a third time, but we're not sure what to do differently. If you could offer any advice/suggestions, it would be most welcome. Thank you!
