Bleeding During Pregnancy
Early-pregnancy bleeding can originate from the uterus, cervix, vagina or the external genital area. Often the cause of bleeding requires no treatment.
Possible causes of bleeding include:
- Implantation of the embryo
- Irritation (e.g., after intercourse)
- (the baby develops outside of the uterus)
- Molar pregnancy (rare growth inside the uterus)
Threatened Abortion Risk Factors
Factors that may increase the risk of threatened abortion include:
- Certain medicines
- Advanced maternal age
- Fetal heart monitoring
- Blood tests
How We Treat Bleeding
If you are bleeding heavily, your doctor may recommend bed rest. This has not shown to be beneficial, though. Your doctor may also want you to limit your activities.
Your doctor may prescribe progesterone, a female hormone that supports pregnancy.
If your blood is Rh-negative and your partner's blood is Rh-positive, your doctor will give you an injection of Rho immune globulin. This will prevent your body from producing antibodies against your fetus' blood.
Have a Healthy Pregnancy
While there is no clear way to prevent threatened abortion, you can take these steps to have a healthy pregnancy:
- Get regular prenatal care
- Avoid alcohol, cigarettes and drugs
- Limit caffeine intake
- Control any long-term conditions that you may have (eg, diabetes, thyroid disorder)
- Talk to your doctor before taking any medicine
- Avoid contact with toxins
