By the third trimester, the placenta should be near the top of the uterus, so that the cervix is ​​clear for delivery

Sometimes, the placenta partially or completely covers the cervix. This is called placenta previa and there are different forms of placenta previa:

  • Marginal: the placenta is on one side of the cervix, but it does not cover the opening.
  • Partial: the placenta covers part of the cervical opening.
  • Complete: the placenta covers the entire cervical opening

The patients who are most at risk of suffering from it are the following:

– Smokers
