What is Plan B™?

Plan B™ is an emergency contraceptive that can prevent a fertilized egg from implanting on the wall of the uterus. It should be taken within 120 hours (5 days) of unprotected intercourse or a birth control mishap (missed pills, condom breakage, etc.). The sooner Plan B is taken, the more effective it is.

Process of pregnancy

Every month during the menstrual cycle, a tiny egg (ovum) is released from an ovary into a fallopian tube. The egg moves along the fallopian tube (where it can be fertilized by the male sperm) to the uterus. A fertilized egg will then implant itself to the uterus wall to allow the development of an embryo.

How exactly does Plan B™ work?

Plan B™ contains a hormone called Progestin (or levonorgestrel). When taken, Plan B™ can stop ovulation from occurring. If an egg has already been released, it can prevent a fertilized egg from implanting itself in the uterus.

When should you consider Plan B™?

• If you’ve had sex without a contraceptive.
• If the condom broke, tore, slipped off or was misused.
• If you’ve missed taking your birth control pills, forgot to put on or change your patch, or forgot to insert or change your ring.
• If you are late in receiving your Depo-Provera.
• In case of sexual assault.

 Procedure

Once you arrive at the Sexual Health Clinic, you will be seen by a nurse who can answer any questions you may have about Plan B™. You will then be given a package with 2 pills which can either be taken at the same time or 12 hours apart to reduce side effects. Both ways are just as effective.

Side Effects

The most common side effects of Plan B™ are nausea, vomiting and irregular bleeding. Other less common side effects include breast tenderness, headache, dizziness, fatigue, lower abdominal pain and diarrhea.

Cost

$10 at the Thunder Bay District Health Unit.

What you need to know

• Plan B is not a replacement for your regular form of birth control, nor does it provide long-term protection against future pregnancy.
• After taking Plan B, your period may not occur at the expected time. If you don’t get your period within 3 weeks after taking Plan B, return to the clinic for a pregnancy test.
