我email咗clearblue, 如檢實係要喺荷爾蒙變化前開始驗, 姐係如果您哋覺得已有排卵徵狀, 想用棒棒確定, 就唔好用CB, 要等新cycle先好用, 供參考:
"If you do not use the product according to the instructions the test may not detect the hormone changes it is looking for. We recommend that you wait until your next cycle and start testing according to the instructions."
