Getting pregnant

So I have been trying to get pregnant since I have been with my now husband so around 4 years and nothing then a family member said she done handstands and put pillows under her after sex for aprox 20 minutes she was trying for a while but insisted thats how she caught pregnant. So I thought what have I got to lose, so I went ahead and absolute first cycle caught pregnant but unfortunately turned into chemical but I was so happy it worked. I was still sad so toke two cycles off 'trying' am now back to trying with handstands. But I read its a myth and gravity doesn't matter? Anyone else have or done this and become pregnant? Any views are welcome. :)
