Are there times when sex should be avoided?

Although most women can safely have sex throughout pregnancy, sometimes it's best to be cautious. Your health care provider may recommend avoiding sex if:

• You're at risk of preterm labor
• 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)
