The morning-after pill will prevent or delay the release of an egg from the ovary if given prior to ovulation, or it will help prevent the egg from traveling down the fallopian tubes and implanting in the uterus if you have already ovulated. The morning-after pill reduces the chance of getting pregnant it does NOT cause an abortion.
Heavy bleeding seven days, 5 or 4 days after taking plan B is considered normal. The bleeding is occasioned by the shedding of your uterine lining, which is exactly what plan B was designed to do. You will find that your next period will pick up in the following month.
However, it is recommended that you do not engage in unprotected sex until your normal cycle is back. If possible, ensure that you get on a birth control method, as Plan B One-Step should only be used as an emergency method, and not as a regular method of birth control. It is always best to practice safe sex as it also reduces your chances of contracting an STD.
In the weeks after taking Plan B, light spotting between periods or a heavier flow are not typically a cause for concern. However, if these issues do not go away within a month or so, something other than Plan B may be responsible.
Heavy bleeding and intense pain can signal a serious underlying condition, such as endometriosis. Also, heavy bleeding can indicate an early miscarriage.
A healthcare provider should assess all heavy bleeding. If a persons periods are irregular and heavy, taking additional hormonal contraceptives can help. If the bleeding results from pregnancy loss, the doctor may recommend surgery to remove remaining tissue.

Most of the girls think about their menstruation date before planning a vacation or a trip or in some of the cases when they are about to get married. No girl wants to face those unbearable pains, cramps, mood swings, and uneasiness which can spoil her vacation or their wedding night.

There are 2 types of emergency contraceptive pills commonly sold in the U.S.:
Editor’s note : Technically, a doctor could have you take higher doses of regular combination birth control pills as emergency contraception, something called the Yuzpe regimen. But that’s not as effective as the other 2 types listed above, and it brings with it more side effects. Additionally, the copper IUD could be inserted within 5 days as a form of emergency contraception.
Scientists have found that both Plan B One-Step that you can get over-the-counter, or the prescription for ella, are safe to use to prevent pregnancy. Any side effects that you have after taking either of the emergency contraceptive pills should be mild and short-term.
After you take emergency contraceptive pills, the most common side effect is – you guessed it – changes to your menstrual periods.
Here is a list of some possible side effects after using a “morning-after” pill like Plan B:
Emergency contraception should be used if:
A few factors play into Plan Bs effectiveness. Doctors recommend taking it within 72 hours after a whoopee whoopsy so you have 3 days to head to the pharmacy and pick it up. If youre already on birth control , you should keep taking that as you normally would.
Research shows that, while its generally effective, Plan B doesnt have a 100 percent success rate. About 7 out of 8 women who wouldve become preggo wont conceive if they take Plan B within 3 days after sex. That means 1 out of 8 will get pregnant.
Plan B may not work if you vomit within 2 hours of taking it. Additionally, body size may come into play. It may be less effective in women who have a BMI over 25 or who weigh more than 165 pounds.
But thats doesnt mean for sure that it wont work.

It is normal to bleed after taking plan B, and as such, there is no reason for you to worry in case you experience bleeding after plan B. Even though this side effect is not very common, these pills contain hormones that could influence the hormones that are already present in your body, and may, therefore, cause some women to start bleeding at unexpected times.
According to Healthline.com, approximately twenty-five percent of all women who take plan B emergency contraceptive pills are likely to notice some changes in their menstrual cycle. As mentioned earlier, you need to consult your physician if this bleeding goes on for more than a few days, as it could mean that there is a serious underlying issue.
“It is common for there to be unexpected or atypical bleeding after taking Plan B,” says Felice Gersh, MD , the medical director of the Integrative Medical Group of Irvine.
Around 15% of people experience bleeding right after taking Plan B, before their period starts. This means that you may have spots , but that your period doesn’t start right away.
In other cases, Plan B can trigger your period to come early , so bleeding may be a sign that it’s working, Gersh says.
Bleeding can start and stop any time in the first three weeks after taking Plan B. The length of your bleeding can vary, but it generally won’t last longer than a few days .
Plan B works by delivering a chemical called levonorgestrel, which mimics the hormones that control your menstrual cycle. Levonorgestrel can stop your ovaries from releasing an egg or stop a fertilized egg from implanting in your uterus.
Taking Plan B can cause bleeding because levonorgestrel changes the stability of the uterine lining that you shed during your period, which can lead to unexpected bleeding, Gersh says.

Yes, Plan B ( levonorgestrel ) can delay your period or cause bleeding to occur outside of regular menstrual bleeding because levonorgestrel is a synthetic hormone. To prevent pregnancy, Plan B, like other birth control pills, must alter your hormone levels, which can prompt these menstrual changes. Plan B is associated with more menstrual changes than regular birth control pills because the dosage is higher.
In a clinical trial, 31% of participants experienced some change in their menstrual cycle after taking Plan B, but the potential menstrual changes are varied. Plan B may cause some women to experience heavier or lighter menstrual bleeding compared to their regular periods.
After taking Plan B, some women get their period sooner than expected, while others get it later. However, clinical trial data suggest most women will get their period within two days to one week of the anticipated time. Women who take Plan B and experience a delay in their period greater than one week are recommended to take a pregnancy test.
During your menstrual cycle, the time at which Plan B is taken can affect how your menstruation changes.
Nonmenstrual bleeding, or spotting, can also occur after using Plan B. Clinical trial data show that 16% of participants experienced spotting in the first week after taking Plan B. Similarly, in one study of 232 women who took Plan B, just under 15% experienced spotting. In this study group, the bleeding typically started around 4 days after Plan B was takenand lasted an average of 2.4 days, with a range of one to seven days. Some women began spotting as early as 8 hours after taking Plan B.
Menstrual changes and irregular bleeding associated with Plan B should go away without treatment. In one study of 132 women, most women returned to their normal cycle length in the next cycle following the use of Plan B. However, those who took Plan B later on in their cycle (after ovulation) had a slightly longer next cycle on average.

In our latest question and answer, the pharmacist discusses when you can expect to get your period after taking the emergency contraceptive Plan B.
I have a question about the effectiveness of the Plan B pill. I am regular with my birth control but was on the sugar pills when secondary measures failed. I took the Plan B pill 17 hours after. I am currently 2-3 days late for my period. With those measures, how long should I wait for my period or what are the chances that I am pregnant? Thank you!
Plan B, an emergency contraceptive containing a high dose of the progestin levonorgestrel, is effective in preventing unplanned pregnancy is taken within 72 hours of unprotected sex. While generally well tolerated, Plan B can cause the following side effects:
The side effect of 'menstrual changes' encompasses a variety of possibilities including:
In most cases, you can expect to get your period around the same time you usually get it. In one clinical trial, most women (~87%) had their period at the expected time or within 7 days. On the other hand, around 13% of women had a delay of more than 7 days beyond the expected date of menses. In addition, a small percentage of women experienced amenorrhea (absence of menses).
Per the manufacturer of Plan B, if it has been more than 7 days from your expected menses, it is important to consider the possibility of pregnancy. You should make an appointment with your doctor to be tested. A 7 day or greater delay doesn't necessary mean you are pregnant as the medication may simply have caused you to miss it. Nevertheless, it is important to be tested.
In terms of effectiveness, you can be pretty confident you were well protected from unplanned pregnancy. Perfect use of oral hormonal contraceptives has a effectiveness rate of over 97%. The use of Plan B within 72 hours of unprotected sex reduces the risk of pregnancy to about 1%. As you used both methods as required, pregnancy would be considered rate.
