Frequently Asked Questions

What exactly is Depo-Provera?
Depo-Provera, often just called "Depo," is a form of birth control given as a shot. Doctors use a hormone similar to progesterone, which ovaries produce naturally. This shot is administered by a healthcare provider every three months.
How does Depo-Provera prevent pregnancy?
This shot works by thickening cervical mucus, making it harder for sperm to reach an egg. Plus, it stops ovaries from releasing eggs (ovulation). Without ovulation, there's no egg to fertilize, preventing pregnancy effectively.
Can Depo-Provera be used right away?
Yes, but timing matters. If you get your first shot within the first five days of your period, it starts working immediately. If you get it at another time, you'll need to use another form of birth control, like condoms, for the first week after getting the shot.
Are there any side effects?
Like all medications, Depo can have side effects. Some folks might experience changes in their periods, weight gain, headaches, or mood swings. Most of these side effects lessen or go away after using Depo for a while.
How long does it take for fertility to return after stopping Depo-Provera?
Fertility doesn't bounce back immediately. For some, it might take about 10 months after the last shot to get pregnant, but it can take longer. Everyone's body reacts differently, so patience is key.
Can Depo-Provera provide protection against STDs?
Nope, Depo-Provera doesn't protect against sexually transmitted diseases (STDs). Using condoms along with Depo is a smart move to protect against STDs.
Is Depo-Provera suitable for everyone?
Not exactly. Certain health conditions might make Depo less ideal. For instance, if you have a history of osteoporosis, breast cancer, or unexplained vaginal bleeding, you should chat with your healthcare provider to see if Depo is right for you.
How do I know if Depo-Provera is the right choice for me?
Choosing birth control is a personal decision and depends on many factors. Discussing your health history, lifestyle, and preferences with a healthcare provider can help you make an informed choice. They can guide you through the pros and cons, helping you decide if Depo fits your needs.
