Depo-Provera is an injectible hormonal method that is given every 10-13 weeks. Each shot lasts approximately three months. Depo becomes effective 24 hours after your first injection and remains effective as long as you are getting your shots on time (no more than 13 weeks apart).
As long as the sex occurred more than 24 hours after you had your shot, your risk of pregnancy is extremely low. Depo is over 99% effective.
Your doctor is correct. Irregular bleeding is the most common side effect of Depo-Provera. After six months to one year of use, some women stop getting their periods altogether while others experience menstrual bleeding every three months.
If you are still worried about pregnancy, purchase a home pregnancy test. Be sure to follow the directions precisely. For best results, use first morning urine and do not drink anything prior to your test.
