I'm interested in trying it. I've posted before about my total un-sortedness - we are supposed to be using condoms but in reality dh gets off at Paisley. Risky! Persona plus condoms on fertile days seems like a good option - and I could carry on using it if we want to ttc again. But it's pricey and even the test sticks cost £9.99 for 1 cycle's worth.
So - do you have to keep using the test sticks for ever? Or do you just do it for a few months til you have got a pattern? And is it a good thing in general?
