Just yesterday I read an article about these (on the BBC I think) that said that 6 months' use is as effective as a round of IVF, so I was intrigued! I looked at their website yesterday and saw their pregnant-in-12-months-or-money-back guarantee, which I like.
However, I'm not sure how much more it could tell me than I get from my Clearblue Fertility Monitor? Does anyone know? I am getting an LH surge each month, so I have a pretty good idea of when my fertile time is and when we should be BDing.
Also, I'm a bit concerned about timing - at 39 and trying for my first, plus diminished ovarian reserve, maybe I'm better off spending the extra doing IVF, rather than waiting 6-12 months using the Duo to see if it works for me.
Would love to see what women who have used it think of it!
