Anyone know if short cycles have anything to with not being able to conceive? I'm out for the month of March. Again :(. & we usually bd on ovulation day. But my periods have only been 3 days for the last 2 years. The flow was heavier than normal this time around. But I can't remember the last time it lasted longer than 3 days. Anyone know if that could have something to do with it? Just curious. T.I.A ladies!
