LIFTING LEGS AFTER SEX TO CONCIEVE

Daija
So ladies, I've heard of the old method that when you're done having sex with your SO that you can put your feet up on the wall for 20-40 mins with a pillow propped underneath of you for positive results of conceiving. I would just like to know how much of this is true and if it's ever helped anyone else conceive that cycle? Any answers would be lovely..
