Pregnancies diagnosed during Depo-Provera useLynn Borgatta et al. Contraception. 2002 Sep. Show
AbstractWe conducted a review of contraceptive failures among women using Depo-Provera (depot medroxyprogesterone acetate), using reports to the Insurance Division of Planned Parenthood Federation of America, Inc. Cases were included if the Depo-Provera had been given at a Planned Parenthood center and pregnancy had either been diagnosed by, or reported to, a Planned Parenthood center. There were 402 reports of pregnancy from 1994 through 1998. The crude rate of reported pregnancies was 0.42 pregnancies per 1000 women using Depo-Provera each year. Pregnancy was diagnosed after the first trimester in 46% of women. Seventy-seven women (19.1%) received additional Depo-Provera injections while pregnant. Of the women whose date of conception could be estimated, 113 of 258 (45%) became pregnant after the injection. There was no observed increase in ectopic pregnancy rate, and no fetal anomalies were reported. Although pregnancy during Depo-Provera use is rare, it does occur. These pregnancies are frequently unrecognized until beyond first trimester. Similar articles

In the US, nearly half of pregnancies happen by accident. Many occur because couples aren't using contraception. However, nearly 50% of unintended pregnancies occur because the birth control failed or the couple used it incorrectly. If you get pregnant while using hormonal birth control like the pill or an IUD, it is important to stop using it as soon as possible. If you stop early on in pregnancy, there is a good chance you won't have any complications. How birth control worksMany birth control methods use sex hormones to trigger changes in your body that prevent pregnancy. Elevated levels of hormones such as progestin, either alone or combined with estrogen, can prevent ovulation as well as thicken the tissue lining in your uterus so eggs can't join together with sperm or implant in the uterine wall. The most common form of hormonal birth control is the pill, which 28% of Americans use to prevent pregnancy. Other methods that use hormones include vaginal rings, patches, subcutaneous implants, injections, and some IUDs. What happens if you take birth control pills while pregnantAccording to the CDC, nine% of people who take birth control pills will become pregnant each year. That's because "although the effectiveness of birth control pills is very high when used perfectly (99.7%), the average woman will occasionally miss doses," says Dr. Yvonne Butler Tobah, MD, an OB-GYN at the Mayo Clinic. Because accidental pregnancy is fairly common from failed or misused hormonal birth control, many developing embryos may be exposed to high levels of progestin and/or estrogen early on in pregnancy. However, research indicates that this will not cause major problems for your health or the health of your embryo. For example, a 2016 study published in BMJ found that there was no link between taking birth control pills while pregnant and having a baby with birth defects. What happens if you get pregnant with an IUDIf you get pregnant with an IUD, it's important to see a doctor and have it removed as soon as possible. Because there is an increased risk that you will have, what's called, an ectopic pregnancy, says Butler Tobah. Ectopic pregnancies happen when the fertilized egg implants itself in the fallopian tube instead of in the uterus. Ectopic pregnancies can be life-threatening and may require surgery as soon as possible. Even if you have a normal pregnancy with an IUD, it may be important to have the device removed within the first trimester of pregnancy, if possible. Talk to a doctor about your options. "Contact your healthcare provider as soon as possible if you think you might be pregnant, even while on a form of birth control," Butler Tobah says, adding that you can also start by taking an at-home pregnancy test.
