I had the same problem with you before. The "chinese doctor" said my body is very cold and wet and my kidney is very weak leading to "OR" and it really affect "bingo". because it make our oval very cool and not warm enough for fertilized egg. so you have to stop drinking cold staff and do not drink vegetable soup.
Even you get "bingo", as the house for the fertilized egg is not warm, easy to "miscarriage".
