Some mothers-to-be are very happy to be pregnant with a twin baby. However, they do not know that the risk of miscarriage is much higher for twin pregnancies in the middle of the pregnancy, around April to July, than for singleton pregnancies, because the size and weight of the uterus in the middle of the pregnancy is already the same as that of a singleton, or even a little bigger. Many mothers who miscarried in this month were encountered in the clinic and it was a great pity. Therefore, mothers of twin babies should pay more attention to rest after 16 weeks, don’t work too hard, no intercourse, less shopping, less stair climbing and don’t lift heavy objects. Increase your resistance and avoid catching a cold. If you catch a cold, you must see a doctor as soon as possible. Pay attention to proper nutrition and take appropriate walks. Try to keep the baby in the mother’s belly for a longer time to reduce or avoid miscarriage.
