Can you fall pregnant on the 3 month injection?
Once you stop having the 3-monthly contraceptive injection, it can take up to a year for you to return to fertility and be able to get pregnant2. However, in most women the effect will have worn off 5 to 6 months after the last injection. Over 80 % of women will conceive within a year of their last injection1.
Depo-Provera has a failure rate of less than 1% when it is used correctly and consistently. When used correctly only 3 in 1,000 women will get pregnant. You should take a pregnancy test if you are experiencing any pregnancy symptoms.
- But to be fully effective, birth control pills need to be taken correctly. Missing even a few doses greatly increases your chances of pregnancy: while only 0.1 percent of women get pregnant when using the pill properly, pregnancy rates soar by 30-80 times when pills are missed.
- The Depo-Provera shot is a highly effective birth control method. Women who use it correctly have a risk of pregnancy that's less than 1 percent. However, this percentage increases when a woman doesn't receive the shot at the recommended times.
- The most common early signs and symptoms of pregnancy might include:
- Missed period. If you're in your childbearing years and a week or more has passed without the start of an expected menstrual cycle, you might be pregnant.
- Tender, swollen breasts.
- Nausea with or without vomiting.
- Increased urination.
When you have the Depo-Provera injection within the first five days of your menstrual cycle, it works 24hrs after the injection. When the Depo-Provera injection is given to a woman after she has given birth, or had a miscarriage or an abortion, it works immediately.

- Common side effects of Depo-Provera include:
- changes in menstrual periods,
- weight gain,
- stomach cramping or pain,
- If you get the birth control shot (also known as Depo-Provera) within the first seven days after the start of your period, you're protected from pregnancy immediately. Each shot will protect you from pregnancy for 12 weeks.
For some women, it can take up to a year after the last shot to begin having regular periods, but for others it can happen as soon as four months after the last shot. In one large study, the average time to get pregnant after discontinuing Depo-Provera was ten months.
- The trouble with having no menstrual cycle is that you don't know if your body is planning to have one in the near future. This means, you could be ovulating in preparation for a cycle that's about to start, or you could be ovulating without having actual periods. Any time you ovulate, you can become pregnant.
- There's a risk of harm to the unborn baby with using Category X drugs during pregnancy, and most doctors agree they should be avoided whenever possible. Getting Depo while pregnant can also lead to low birth weight, though studies have shown that this risk doesn't necessarily cause any problems later in life.
- For some women, it can take up to a year after the last shot to begin having regular periods, but for others it can happen as soon as four months after the last shot. If you are thinking of getting pregnant within the next few months, Depo-Provera is probably not the best birth control option for you.
