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

Are there times when sex should be avoided?

Breast stimulation, female orgasms and certain hormones in semen called prostaglandins can cause uterine contractions.

Your health care provider might recommend avoiding sex if:

  • You have unexplained vaginal bleeding
  • You're leaking amniotic fluid
  • Your cervix begins to open prematurely (cervical incompetence)
  • Your placenta partly or completely covers your cervical opening (placenta previa)
  • You have a history of preterm labor or premature birth
