Hi am a bit confused by the dual hormone clearblue kit I'm using. I didn't have a high fertility reading this month but went straight to peak fertility yesterday. Wondered if it was incorrect as I had had a wee during the night so thought I'd check again today. But the smiley face hasn't cleared. On the leaflet it says the peak fertility symbol will stay for 2 days - which I thought meant would appear on two tests - but now I'm thinking it means will literally stay on the monitor for 2 days? Doesn't really matter as dh is away anyway but am just a bit confused by the instructions!
