has anybody seen this fertility friend glitch?

Question

I've been tracking my cycles with fertility friend lately. I have a pretty normal 28 day cycle and i've had it since i first got my period when I was young. On fertiltiy friend, it says i have a 31 day cycle. i think there is a glitch that doesnt accomadate the 28 days in the month of february, and still calculates it as if there were 30 days in that month. my most recent periods were: Jan 13, Feb 10, March 13. I started charting after the feb 10 period, here is a link to my chart. http://www.fertilityfriend.com/home/19402f

has anybody heard of this type of glitch?? it does it in "my monthly cycles.com" too..

will this glitch thing throw my chart off??

thank's a bunch!

Answer 1

Your Jan. cycle was 28 days and your Feb. cycle was 32 days and FF and MMC take an average--and the average of 28 and 32 is 30. There is no glitch, it just averages your cycles.
