Hi,
Depo-
Provera is a birth control shot that contains the hormone progestin, which works by preventing ovulation and thickening the cervical mucus to prevent sperm from reaching the egg. One of the side effects of Depo-Provera is that it can cause changes in menstrual cycles, such as irregular bleeding or missed periods.
Since you received the Depo-Provera shot eight days after your period started, it is unlikely that you would become pregnant from any sexual activity that occurred before the shot. However, the shot can cause changes in your menstrual cycle, including a delay in your period. It is also possible for irregular bleeding or spotting to occur during the first few months of use.
If you are concerned about a possible
pregnancy, you can take a pregnancy test to confirm. However, if you have been using condoms consistently and correctly and received the Depo-Provera shot as directed, the chance of pregnancy is low.
It is important to remember that Depo-Provera is not 100% effective at preventing pregnancy and does not protect against sexually transmitted infections (STIs). If you have any concerns or questions about your birth control options or menstrual cycle, it is best to consult with your healthcare provider.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Priyanka, General & Family Physician
