would appreciate some advice - my cycles are between 31 - 36 days and and am thinking about going to see the Dr. If I have a day 21 test what day should I have it to see if I am ovulating with my cycles? My last 3 cycles have been 36 days, 36 days, and 33 days respectively. I am currently on CD 18 and still only getting lows on the CBFM.
Many thanks
