Like Darkestlight mentioned an ovulation test would probably be your best bet. Most women (not all) ovulate some where in between their cycles. for example your is 22 days so you would generally ovulate around CD 11 . but thats only if you ovulate at the same time evrey month. Than you start BDing around CD6 every 2 days than the day of ovualtion. But since most woman dont know when they ovulate the ovulation tests are great. I have never tried them personally I generally know when I ovulate cause I have a mild cramping on one side by my ovaries when I do. Good luck with everything!! I noticed you were hoping for a boy........it doesnt always work out the way we want it, lol. Trust me I have 3 boys and 1 (unknown gender) on the way. But I wouldnt change them for the world:)
Sounds like ur best bet would be to invest in ovulation tests.
