Plan B One-Step is a type of morning-after pill that can be used after unprotected sex to prevent pregnancy. Plan B One-Step contains the hormone levonorgestrel — a progestin — which can prevent ovulation, block fertilization or keep a fertilized egg from implanting in the uterus.
The sooner you take Plan B®, the more effective it is. It can prevent pregnancy if taken within 72 hours and preferably within 12 hours of unprotected sex. If you take it within 24 hours of unprotected sex, it is 95% effective. If you take it between 48 and 72 hours of unprotected sex, the efficacy rate is 61%.
Emergency contraception is safe. Even though it's made of the same hormone as the birth control pill, the morning-after pill does not have the same risks as taking the pill or other hormonal birth control methods continuously.
the length of your menstrual cycle – ovulation usually occurs around 10 to 16 days before your period starts, so you may be able to work out when you're likely to ovulate if you have a regular cycle. your cervical mucus – you may notice wetter, clearer and more slippery mucus around the time of ovulation.
Plan B cannot cause a miscarriage nor hurt you if you are already pregnant. If you DO NOT get any vaginal bleeding within 3 weeks after taking Plan B, call the Health Center at 685-2470 for an appointment.
A woman's ovulation cycles can vary, so it's statistically possible you could become pregnant while on your period. While pregnancy is less likely in the earlier days of your period, the chances increase in the later days.
Emergency contraception (EC), also known as the morning-after pill, will not harm a fetus. Still, women should not use EC when they're pregnant. EC does not end a pregnancy — it can reduce the risk of pregnancy if started within 120 hours (five days) of unprotected intercourse.
The Morning After Pill comes with a pregnancy test. No urine pregnancy test will show positive until 7 to 10 days after conception; therefore, a positive pregnancy test at this point means that the woman is pregnant from an earlier sexual encounter.
Plan B can trigger your period to come early, so bleeding or spotting may be a sign that it's working, Gersh says.
Some women might experience the first symptoms a week or two after conceiving, whereas others don't feel anything for months. Many women may tell if they are pregnant within two or three weeks of conceiving, and some women know a lot sooner, even within a few days.
Levonorgestrel is found in birth control pills, but Plan B contains a higher dose that can alter your body's natural hormone levels. The extra hormones can, in turn, affect the menstrual cycle, leading to an earlier or delayed period as well as heavier or lighter bleeding.
The only way to know if the morning after pill has been effective at preventing pregnancy is if your next period arrives when it should. The morning after pill works by delaying ovulation so that you don't release an egg for remaining sperm in your system to fertilize.
If you've accidentally taken 1 extra contraceptive pill, you don't need to seek medical advice and you will not have any symptoms. If you've taken several extra pills, you may: feel slightly sick. be sick (vomit)
How Much Is Plan B? It ranges between $40 and $50, typically. There are cheaper generic alternatives, such as After Pill, which is $20 plus shipping or Take Action or Next Choice One Dose, which may be up to 20% cheaper than Plan B.
Plan B has a weight limit of 155 lbs, but it's still safe to take morning-after pills even if you fall above the recommended weight limit. Although there's a chance they might not be as effective, it's not likely to pose any health risks.
Plan B does not have a weight limit that prevents people with a higher body mass index (BMI) from taking it. It is still safe to use in individuals with a higher body weight, and it will still substantially reduce the chance of pregnancy when a person uses it within 3 days of having unprotected sex.
The results of a large European study show that the popular form of EC, levonorgestrel 1.5 mg, (Plan B pill) loses its potency in women weighing about 165 pounds and does not work at all in women weighing 175 pounds or more.
The most effective choice for emergency contraception for overweight or obese women is the copper IUD. The effectiveness of the copper IUD used as EC is greater than 99%, no matter how much you weigh (and it provides at least 10 years of excellent ongoing contraception).
