Emergency contraceptive pills, or morning-after pills, are a type of birth control that you take to prevent pregnancy after unprotected sex. “You might have irregular bleeding when you first go on the pill, so I usually have people wait four to six months before we discuss switching,” says Almeida. “With bleeding irregularities, it can take time for the body to regulate.”
Hormonal birth control is highly effective at preventing pregnancy when used consistently and correctly. According to the NCI, people who have used the pill for at least 5 years may have an increased risk of cervical cancer compared to people who have never used the pill. Some research suggests that low dose combined pills can negatively impact bone mineral density (BMD) in adolescents and young adults.
Research is mixed on whether the IUD increases the risk of breast cancer. A review of more than 40 studies found no link between the pill and weight gain. That doesn’t mean the bathroom scale won’t tick up a little.

The risk is considered temporary as it declines after you discontinue use. The combined pill, patch, and vaginal ring can increase your blood pressure.

Most of the research looking into the link between them and cancer comes from observational studies. According to the National Cancer Institute, these studies can’t definitively establish a link between birth control pills and cancer.

- About 22 out of 100 people (22%) using Kyleena develop an ovarian cyst, compared to about 14 out of 100 people (14%) using Skyla.
- Overall, the most effective form of hormonal birth control is the implant or IUD, which boasts a less than 1% failure rate.

“I debunk myths about birth control on a daily basis,” she says. “Before making decisions about hormonal birth control, it’s important to do your own research and speak with your doctor to help separate fact from fiction.” In other words, don’t trust someone if you don’t know their credentials and what makes them qualified to discuss the topic. If you come across an article on a website, make sure it has .edu or .org after the name, and read the About page to see what type of website it is. Almeida also suggests looking at the Centers for Disease Control and the American College of Obstetrics and Gynecologists for information about hormonal birth control.

Your doctor may start you on this level and then change it if side effects bother you. You have less than a 1% chance of getting pregnant if you use them exactly as directed. According to Almeida, that’s OK as long as you’re searching reputable sites and doing the research. “You want to look at who wrote the article and see if that person has MD after their name,” she notes. “It’s also a good idea to check the references at the bottom of the article.” You can also track your basal body temperature (your body temperature at rest) within some apps or use a wearable.
Your healthcare provider will discuss any concerns you have. They’ll talk to you about any risk of complications based on your medical history.

How to Take Birth Control Pills
If a person suspects that they may be pregnant, it is best to take a pregnancy test. The birth control pill is effective, but pregnancies can occur, especially with improper use. However, this side effect can depend on the formulation of the birth control pills. For example, those containing drospirenone and low estrogen types may be less likely to cause mood changes than other formulations. Planned Parenthood notes that studies have shown that the birth control pill does not generally affect a person’s weight.
