TTC tips that work?

Ok so I've heard that when TTC it can help if after you "do the deed" to lay down with your pelvis elevated on a wedge/pillow so as to help the umm baby gravy (lol) make its way... Has anyone actually tried this? Does it help? My SO and I have started talking about TTC (#2 for both of us) and I'm so excited I'm trying to find any and all extra little things to do to possibly help the process...
