Noooo! BD once is girl territory! Shettles was sadly a joke...my DS3 is a Shettles opposite...wouldn't trade him for anything now, though at the time I was cursing Dr. Shettles. LOL.
For a boy, you want to try to build up sperm count...dtd every other day is actually best & if you know when you ovulate, I'd work around that. For us, BD every day resulted in a boy...next time, we'll be releasing twice a day to lower count to TTC a girl.
Thanks! My boys really are sweet...I just really want a baby girl, too. :)
Wishing you lots of luck!
