With 4 weeks now until my consultant appointment where we will hopefully be referred for IVF, I've decided we will give it a blummin good go this month. CD1 today so thought I'd buy some cheapy OPKs. My cycles are a little bit erratic and I have a CBFM but gave up using it a while ago as it just wasn't really helping.
Anyway, there are loads of OPKs on amazon, which should I get and how often/how should I use them? i.e. time of day, once or twice a day and from when? Never used them before so any advice welcome!
