Any type of bleeding in pregnancy needs to be reported to your doctor or midwife immediately, it is a pregnancy warning sign. But what are the possible reasons for bleeding in pregnancy?

Early Pregnancy

  • Miscarriage
    This is the loss of a pregnancy prior to 20 weeks gestation. It can be a genetic complication, blighted ovum or other complications.
  • Implantation Bleeding
    This is when you have spotting that occurs very early in pregnancy as the pregnancy is burrowing into the uterine lining.

Later Pregnancy

  • Placental Abruption
    This is an obstetrical emergency when the placenta is separating from the uterus.

(These times are most common but can certainly happen in other parts of pregnancy in some cases.)

If you experience bleeding, your practitioner will most likely ask you to come in to be seen. You may have an ultrasound and/or blood work done as well as a vaginal exam.

This will help your practitioner determine the cause of the bleeding and what steps need to be taken.
