"If" everything is a go in your body and no fertility problems exist (this includes the guy as well) then yes, as long as you ARE ovulating.. that is the key.. well and fertile cervical mucus.... Do you chart your cycles and too, they may not be two months apart via an actual calendar, but if you sat down and charted, could be your periods are just really long .. ?? (which for some is normal) esp if they have always been that way.. There are many sites where you can learn to chart, like fertilityties.com and yourdays.com
also, a book called take charge of your fertility is quite informative.
best of luck to you
