If we don't have to do any way to protect the fetus, but just think that after pregnancy, I will lie on the bed, then this way, in fact, I personally think it is not a very wise approach.
That is to say, pregnancy should be a very natural state, nature also has a process of survival of the fittest, after becoming pregnant, no matter what kind of situation occurs, lie on the bed and do not move, then this can not be fundamentally solved.
Then some problems are lying still in bed, it is inevitable to miscarry, for example, the embryo itself is defective, even if lying down, it is impossible to solve it by bed rest, the abortion is still to miscarry, so this way is not advisable.
And there are some hazards, such as not moving in bed, then to the family, to yourself will cause harm, some people's physique is a state of hypercoagulation, no longer exercise, inactivity, blood circulation will also appear obstacles, so this way is not advisable.
