Supposedly, with proper use of an IUD, the chances of getting pregnant are less than 1%. Yet in spite of its high efficacy, uptake of intrauterine contraception in the UK, as well as other countries, is low. Experts believe that contraception myths about the method may contribute to the low uptake.
Contraception Myth #3: The Morning-After Pill Doesn’t Work for Heavier Women
Also known as “Plan B” or the emergency contraception pill, the morning-after pill is taken after sex to prevent pregnancy. Since it is not regular contraception, the pill should only be used in emergency situations. Some of these situations include after having sex with no “barrier,” if a condom broke during sex, or if a woman forgets to take a birth-control pill before or after sex.
Despite being a highly effective method, there has been a myth that the morning-after pill does not work as well for heavier women. Researchers emphasize the need for more research to determine whether a higher weight and BMI decreases the effectivity of Plan B or not. At present though, women are free to take it, no matter how much they weigh.
