Hiya,
I used mine for nearly 6 months and i actually credit it for getting me pg as according to chart/dates I was to ov 3 days later than the cbfm said.
I have since miscarried (unfortunately) and i have to wait for my first period til I can start using it again, but for me its been really useful. I would also add I've always been very regular so i dont know if that could have been a contributing factor for it working so well for me.
As far as the 6 month mark I am a bit surprised the manual says that as I was aware the advice is to go to a doctor after 6 months ttc if you are over 35, which i am

. However, i suppose its good advice anyhow, if you are having no luck and finding it a bit stressful (we all do at one point or another) you can get some answers if you speak to a doctor as opposed to worrying needlessly something might be wrong.
There are loads of statistics on the lenght of conceiving , but as lot of the girlies on here can testify to, it can take some time, unfortunately
Good luck and let us know how you're getting on!
