MYTH: The "morning after" pill is not available to minors without a prescription
As of April 2009, Plan B is available to women ages 17 and up, nationwide, over the counter without a prescription. (You just need to ask the pharmacist.) It has been available over the counter for those 18 and up since 2006, while individual states could make their own rulings about availability to minors.
MYTH: Birth control pills make you gain weight
Although clinical trial after clinical trial has been unable to prove a correlation between oral contraceptives and weight gain, this is still a common belief among women of all ages.
MYTH: IUD birth control is not safe for use in teens
Intrauterine devices (IUDs) are small objects inserted through the cervix and placed in the uterus to prevent pregnancy for up to 12 years. Because you don't need to take a pill every day when using an IUD, it can be a convenient and long-term way to prevent pregnancy.
MYTH: If you get the HPV shot you're safe from cervical cancer
Gardasil and Cervarix are cervical cancer vaccines that block the two types of human papillomavirus (HPV) that most frequently cause cervical cancer. Gardasil also protects against two types that cause the majority of genital warts. But about 30% of cervical cancers will not be prevented by these vaccines, so it's important for all women, whether they've gotten the shot or not, to continue having regular Pap tests.
MYTH: Douching is a healthy way to clean the vagina
The vagina is self-cleansing, and douching actually causes more harm than good, according to The National Women’s Health Information Center. The natural bacteria found in the vagina help keep it clean and healthy, and douching can disturb that balance and spread vaginal infections into the fallopian tubes, uterus and ovaries. Additionally, douching does not protect against sexually transmitted diseases or pregnancy. In fact, douching makes it easier for a woman to get pregnant because it pushes semen farther up into the vagina and cervix.
