When i was tracking my ovulation i also use strip & clearblue. The strip one can be quite inacurate. Cs i bought 2 diff cheap brands, both different result. One is dark, the other is not so dark. The best strip is coffoe ovulation strip i bought from shopee, very accurate. As when its dark, i would test my clearblue and would also show either blinking or the smiley face. I would trust the clearblue more. Its okay mummy, continue trying! Dont lose hope ! Not everything you see on internet applies to everyone.
