Emergency Contraception

While different combinations of birth control pills have been used for emergency contraception, the most common one used is Plan B.

Plan B

How it works:

The method of actions is not exactly known. This method may postpone ovulation or stop fertilization. It may also prevent implantation of the embryo. Many consider this to be an aborton method because the pills may act by preventing implantation of the already fertilized egg.

Limitations:

• needs to be taken 72 hours after unprotected intercourse
• In most states, a prescription is required if you are under 18
• cannot be used with a confirmed pregnancy test or undiagnosed abnormal vaginal bleeding

Side Effects:

The incidence of side effects is less than with combined oral contraceptive pills. The most common side effects are naseau and vomiting. Other side effects may include menstrual irregularities, breast tenderness, headache, abdominal cramps, and dizziness.

Effects on Developing Embryo/Baby:

Little research has been done on the effects of taking progestin during pregnancy. However, it has been noted that when women who are unknowingly pregnant take oral contraceptives (levonorgestrel), there is no increased risk of genetic defects.
