hi ladies, just want to offer a positive story - my cycles have always been long and irregular when off the pill, 5-8 weekly, and i never knew when i ovulated. as soon as i came off the pill i started with cbfm as felt that leaving it to chance would take ages.
In our 6 months ttc, i ovulated 3 times and managed to catch each time which in itself was a relief, just knowing we were doing all the right things. The time we conceived my cycle was longer than 6 weeks (which cbfm doesnt work for) and after the cbfm had run out for the month, i carried on with opks and caught the ovulation time shortly after.
technically speaking, then the cbfm wasnt the reason i got pg but im sure it could well have been on another cycle - it was fab having that guidance. did spend a lot on these products but our lovely 8 month old son is worth all of it, and im sure we'd have been ttc at least twice as long without them.
Also, the month i conceived had started on agnus castus - although i think this was coincidence as it was my longest cycle yet and hadnt had time to kick in probably x
