I don't have the monitor LL I have the clearblue digital OPK thingy.
It costs about £23 quid and comes with 5-7 test sticks, I think.
The CB fertility monitor costs about £70!!
There are no replacement sticks for it though.....until I discovered the Persona ones work in it hehehe!
The smiley face tells you that you are about to Ovulate, otherwise you just get a blank circle.
Test with late afternoon wee, i do it about 6-8pm.
When to start during your cycle depends on how long your cycle is I think, but the instructions are quite good.
This month I think i'm going to start testing a bit earlier though because of the ewcm (just had to wipe again), have a mild crampy feeling so maybe it will be earlier this month.
Hope so .
Diege I'm sure they will welcome you. 4 is a bit daunting when I stop and think about it lol
Was planning to jump Dh tonight anyway
