When it comes to birth control methods like the Pill, you know there are things you have to do on your end to ensure effectiveness. That's why many women chose alternate approaches like Depo-Provera -- administered via injection from your physician every 12 weeks, eliminating the daily contraception management. Show The consequences of incorrect usage are out of your hands. Because of this, Depo-Provera is a highly effective method of birth control, with an approximate 99 percent success rate. Only about 3 in 1,000 women will become pregnant while on the contraceptive [source: American Pregnancy Association]. However, even the best birth control can fail on rare occasions. So, yes, there is a very slight possibility you can get pregnant on Depo-Provera. What exactly is thishormonal contraceptive? Much like the Pill, it prevents ovulation and makes the cervix and uterine lining hostile to sperm and fertilized eggs. It uses a synthetic version of the hormone progesterone to achieve these results. Unlike the Pill, your physician will give you a shot, usually in the arm or buttocks. If Depo-Provera shots are received on a recommended basis, pregnancy is highly unlikely. While the contraceptive has the power to prevent conception up to 14 weeks, the injections are usually given every 12 weeks to ensure that there is no gap in the effectiveness of the birth control between shots. When such a schedule is maintained, pregnancy while on Depo-Provera is extremely rare [source: DiLeo]. While there is a very slight risk of ectopic pregnancy (a pregnancy in which the fetus develops outside the uterus) if a woman conceives while on Depo-Provera, it's less likely to occur with this birth control method than it is with others [source: New Mexico Department of Health and Family Planning]. Damage to the fetus is also unlikely. A study of newborns who were exposed to Depo-Provera while in the womb found that there was no significant difference in birth weight or birth defects compared to other babies [source: Dahlberg]. Further research found that Depo-Provera doesn't impact the long-term development of children who were exposed to the contraceptive while in the womb [source: Pardthaisong]. Now that you know about Depo-Provera, keep reading for lots more information on birth control on the next page.

Medically Reviewed by Traci C. Johnson, MD on July 12, 2020 Almost half of the over 6 million pregnancies in the United States every year are (whoops!) accidents. A lot of the time, it’s because people skip
birth control or don’t use it like they’re supposed to. But about 5% of the time, women using reliable birth control find themselves unexpectedly pregnant. This is because while all of these methods have a “perfect use” rate, the “typical use” rate is much lower. Day-to-day life can be so
hectic that it’s easy to forget to pop a pill, replace a patch on schedule, or even get a birth control shot. Here’s a look at the effectiveness of the most common types of birth control and how you can lower your chances of a surprise pregnancy. Oral
contraceptives contain hormones that stop ovulation. If you use them perfectly, they’re a great way to prevent pregnancy, with a 99.7% effectiveness rate. But in reality, a lot of women forget to take them every day, so the typical use rate is only
91%. Other reasons why your pill might not work include: If you have any of these issues, talk to your doctor about using
condoms as a backup method, or switch to another form of birth control entirely. If you skip a dose, take it as soon as you can. If you’ve missed more than two pills, take them as soon as you remember, and continue to take pills daily while you use a backup
method of birth control like condoms for the next week. If you’re on the mini-pill or the progestin-only pill, take it within the same 3 hours every day (For example, if you normally take one at 7 a.m. and then take it after 10 a.m. one day, you’re more likely to
get pregnant). These work similarly to the birth control pill. You either insert a ring into your vagina
(Annovera, NuvaRing) or place a patch on your belly, upper arm, buttocks, or back (Ortho Evra). Like the pill, they’re over 99% effective when you take them exactly like
you should. But if you don’t, they’re only 91% effective. They can fail because: If you use one of these methods, and it falls off or you forget to change it in time, reinsert or replace it within 48 hours. (If it’s been more than 2 days, use a backup method for the next 7 days.) You get
Depo-Provera, or the birth control shot, every 3 months. It contains the hormone progestin, which stops ovulation. With perfect use, it’s 99.8% effective. Sometimes people forget to get an
injection on time. It’s important to get your follow-up shots within 10 to 15 weeks after your last one. If you wait longer than that, you’ll need to use a backup method of birth control for a week. Birth Control ImplantThis is a thin, matchstick-size rod that your doctor inserts into your arm. It releases hormones that prevent pregnancy for up to 3 years. It’s virtually foolproof, since it’s already in your body and you don’t have to remember to take it or to use it the right way. As a result, both the typical and perfect use is over 99.9%. If you’ve had your implant for 3 years and you still don’t want to get pregnant, you have to replace it. Otherwise you could end up with an unexpected little bundle of joy. IUDS -- which your doctor inserts into your vagina -- prevent sperm from reaching an egg. They’re more than 99.2% effective whether you use it perfectly or not. Unlike other forms of birth control, you can’t forget to take it
or use it the wrong way. Once it’s in, you’re protected from pregnancy for anywhere from 3 to 10 years. There are two types of IUDs: copper (ParaGard) and hormonal (Kyleena, Liletta,
Mirena, and Skyla). If you do get pregnant, it’s usually because the IUD has slipped partly or completely out of the uterus. If this happens, see your
doctor immediately. There’s a higher risk of life-threatening complications such as ectopic pregnancy, in which the egg implants outside of the uterus. You’ll need to get checked for this. Even if the pregnancy is in the right place (the uterus), the doctor will still need to try to remove the IUD as there can be an increased risk of miscarriage if it’s left in place. Vaginal contraception is inserted into the vagina prior to sex to create an inhospitable environment for sperm so it won’t reach the egg for fertilization. These come in several forms including foam, jelly, tablet, cream, suppository, or dissolvable film. Normally, during sex, the vagina’s PH level rises to allow sperm to move towards the reproductive canal. Spermicides contain chemicals which kills the sperm before it makes its journey. A new prescription non-hormonal gel called Phexxi keeps the PH level of vagina
at its normally acidic level, causing the sperm to die without progressing. Each of these methods has to be used prior to sex and given time to have the desired effect within the vagina (usually 15 minutes). If used properly, spermicides are 70-80% effective but work better when you combine it with a condom or diaphragm. Phexxi is
considered 86% effective when used correctly. Barrier MethodsBarrier methods of birth control like the diaphragm, cervical cap, or male or female condom physically block sperm from entering your uterus. They’re much less reliable than hormonal methods of birth control -- the male condom, for example, is 98% effective with perfect use, but only 82% otherwise. That means 18 women who regularly use condoms with their partner will end up pregnant within a year. Condoms often break or aren’t put on correctly. These methods work better if you pair them with spermicide, a type of birth control with chemicals that stop sperm from reach an egg. Also called “natural family planning” and the “rhythm method,” these help you track your menstrual cycle so that you know when you’re ovulating. To do this, you take your temperature every day, check your cervical mucus, or chart your cycle on a calendar. If you use at least one
of these methods, and you follow it perfectly, there’s less than a 5% chance you’ll get pregnant. But that can be tough for most women, which is why the typical effectiveness rate hovers around 76%. If you use multiple FAMs together, they’re more likely to work. But this still isn’t a good option for anyone who has irregular menstrual cycles. If you miss a period, take a
pregnancy test to make sure that you’re not pregnant. Other signs include tiredness, bloating, having to pee a lot, moodiness, nausea, and tender, swollen breasts. Most pregnancy tests will be positive by the time you miss your
first period, but if yours isn’t, it’s still important to see your doctor if you’re more than a week or two late to rule out any other health conditions and to confirm that you aren’t pregnant. How do I know if Im pregnant on depo?Signs of pregnancy after depo
Fatigue. Nausea. Tender breasts. Mood swings.
How likely is it to get pregnant on the depo shot?When used perfectly, the birth control shot effectiveness is more than 99%, meaning less than 1 out of every 100 people who use it will get pregnant each year. But when it comes to real life, the shot is about 96% effective, because sometimes people forget to get their shots on time.
