TTC after MC..x (Positions when TTC!!)

Sidra • Baby #1 after MC in Jan2014.
Hey ladies. I'm 22 and fell pregnant early December but then at 9 weeks lost our baby. Me an hubby are now actively trying. I had 1 normal period then missed a whole cycle! & now finally came on again & hoping to try again. One massive question. Does the position your in during sex matter? Or isit a Myth?xxx
