Eating crabs will not directly cause the fertilized egg to fail to implant in the uterus. However, because crabs are relatively cold in nature and have the effect of invigorating blood circulation and removing blood stasis, the embryo is not very stable during or shortly after the implantation of the fertilized egg, as the fertilized egg is not very closely connected to the uterus. If you eat a lot of crabs during this time period, there is a risk of causing miscarriage symptoms. So in order to avoid this possible accident, it is generally recommended to try not to eat crabs in the first 3 months of pregnancy, especially not in large quantities. During the period of time when the fertilized egg is lying on the bed, you should also pay attention to rest, don’t overwork, don’t eat too much of other cold and spicy stimulating food, don’t engage in strenuous exercise, don’t smoke, don’t drink alcohol.
