It is best to create a maternity health card in the third trimester after pregnancy. The purpose is to be able to systematically give the check-ups and follow the times written on it so that there is no chance of forgetting the time of the check-up. In addition, it is possible to give the next doctor the results of the previous examination and then compare them accordingly, so that you will know how much has changed between the previous examination and this one, such as whether the weight, uterine height and abdominal circumference have grown normally. It is very beneficial and convenient for the pregnant woman herself to have a maternity health card. Whenever you go to the hospital for a checkup, make sure to bring your maternity health card so that your doctor can use it to find out what happened in the past.
