I didn't try to sway gender at all with either pregnancy, but found it interesting a friend of mine who used a doner was told she would most likely get a girl because of where she was in her cycle. He told her the male sperm due quicker so if you are exposed to sperm closer to your O date you are more likely to get a boy.
I never would have believed this but thinking about it, DD we DTD earlier in my cycle and DS (current pregnancy) I actually thought I had missed my O date and was geared up for a BFN.
(I know it was that particular session of DTD that got us DS as it was only once that month we didn't use protection / we decided we wanted number 2 pretty out if the blue)
Anyone else done this/noticed this?
