Pregnant women must pay attention to the state of their bodies after consuming crabs and should not be careless within a week. If a pregnant woman does not experience any abnormal symptoms within a week, she can rest assured that the crab has no effect on the fetus. Crab is a cold food, with the effect of activating blood circulation and removing blood stasis, some pregnant women are prone to miscarriage after consumption. However, pregnant women will not experience miscarriage immediately after consuming crabs because it takes some time to digest and absorb crabs in the body, and the coldness of crabs will not have an immediate effect. Therefore, within a week of consuming crabs, pregnant women should pay attention to the state of their bodies, and if there are no signs of miscarriage within a week, then it can usually be proved that there is no serious harm. However, if symptoms such as restlessness of the fetus, vaginal bleeding, abdominal pain, etc., occur within a week of consuming crabs, and if the pregnant woman has not been hit by trauma, it is often considered to be caused by the consumption of crabs. In this case, you should go to the obstetrics department of the hospital in time and actively check the status of the fetus to avoid any danger.
