AF comes like clock-work on the 20th each month. Been off the pill for a year and spent 9 months not really trying very hard and having a husband who travels a TON and always during my "fertile window". We finally got a few good BD days in during my window nearly two weeks ago. I honesty put the whole TTC plan out of my head, concentrated on work/home and literally forgot. Am I a weirdo for being able to forget about obsessing over the calendar?
