Sex during pregnancy: What's OK, what's not

Are there times when sex is not OK?

Having sex or having an orgasm can cause the uterus to contract. This most often isn't a reason to worry.

But your healthcare professional might suggest not having sex if:

  • You have vaginal bleeding.
  • You leak amniotic fluid.
  • Your cervix begins to open early, called cervical incompetence.
  • Your placenta covers your cervical opening partly or all the way, called placenta previa.
  • You have a history of starting labor early or giving birth early.
