Hi all, This is my first post. We have been ttc for 18 months now and so far 1 loss at 6 weeks 12 months ago. I have irregular periods ranging from 24-48 days (mostly 30's) and i was wondering if i would be best to use the clear blue digital ovulation kits or if to invest in a CBFM? IV used the digi's for bout 3-4 cyles so far but nothing so far. if i use the CBFM does it test you each month or presume each month will be the same? will it work with my irregular periods? Any comments / success stories welcome.
