Pregnancy examination as directed by your doctor

Stitching the waist of the uterus during pregnancy does not affect the development of the fetus and is carried out quite quickly so the mother does not need to worry too much. What you need to worry about is how to take care of your uterus waist to ensure your safety later on through some of the following notes:

  • Minimize movement and movement at least within the first week, it is best to lie in bed only, especially in cases where there has been a history of miscarriage, premature birth before.
  • In addition, proper nutrition for pregnant women (with a full range of essential nutrients such as protein, starch, grease, vitamins and minerals) should also be taken care of and implemented.
  • Absolute abstinence from sex during pregnancy at this time.
  • Pregnancy and ultrasound examinations to measure cervical length regularly and additional progesterone can be taken continuously until the 36th week of gestation.
  • When the date of birth is near (approximately greater than 38 weeks), the mother must have a suture before signs of labor to avoid a cervical rupture. However, in cases of majeure such as early labor, early stitches will be cut to avoid tearing and cervical rupture due to sutures during labor.
