Please urgent. Please guide me the possible ways to prevent miscarriage as my wife experienced once. Previously we tried and after her period date covered we tested and found, she is positive. But from very next day. Blood clotting started to come out whenever she urinated. And ultimate miscarriage happened. This time we tried and we do not want to face the same issue. So please suggest me that blood does not comes out and foods that she should not take before and during pregnancy. Thanks.
