hi guys I came off the pill after 14 years a 7 months back and started TTC last month. my last cycle was 33 days long (this is an improvement thanks to acupuncture, the one before was 52!!) last month i ovulated on cycle day 21 but fertility friend has me down as fertile today (CD 16) even though my predicted fertile period is not until CD 19. does anyone know if this is just generic, otherwise I don't understand why they have me down as fertile today as I am 5 days off ovulation according to past cycle please help! this is a minefield!!
