Can Plan B Mess Up Your Period

You Might Experience Medication Interactions

Does the Morning After Pill Affect Your Period?

Plan B is available over the counter, but that doesn’t mean it’s always a good idea to take it without consulting a medical professional first. In fact, it might not be as effect if you’ve taken certain medications, including barbiturates, St John’s wort, and certain HIV/AIDS medications, Dr. Patel says, “so check with your pharmacists about medication interactions.” Even if you don’t think your prescriptions or supplements are on this list, check anyway. It’s always better to be safe than sorry.

What To Expect After Using Plan B

Plan B has shown no long-term consequences or issues, and its safe for almost every woman to take, even if youve been taking another birth control pill. In the days and weeks after taking Plan B, you may experience mild to moderate side effects. For some women, the side effects may be more severe than for others. Some women experience no problems at all.

After the initial wave of side effects, you may experience changes in your period for a cycle or two. If these changes dont resolve, make an appointment with your doctor to discuss what other issues might be occurring.

Plan B is highly effective if taken properly. However, it is only effective as an emergency contraceptive. It shouldnt be used as routine birth control. It isnt as effective as other forms of birth control, including birth control pills, intrauterine devices , or even condoms.

What If My Periods 2 Weeks Late After Plan B

Plan B is 95 percent effective if taken within a day after sex and 88 percent if taken between 3 days after. But theres always a slim chance it wont work.

If you take Plan B and your period is over a week late, theres a slight chance that you might be pregnant. Take a pregnancy test to play it safe.

If its been 2 weeks, your pregnancy odds are even greater and you should likewise take a test. If your pregnancy test is positive, visit a doctor or midwife to confirm your result and walk you through your options.

If youre not sure what stage of your cycle youre at or you have irregular periods, Planned Parenthood recommends waiting 3 weeks after taking Plan B before you take a pregnancy test.

Pregnancy tests measure the hormone human chorionic gonadotropin , which the body starts to produce a few days after conception. So if you take a test too early, it could show a false-negative result.

If your period is still MIA 2 months after taking Plan B, you could be pregnant. Its unlikely its the EC still messing with your cycle.

Take a pregnancy test and visit a doctor or midwife ASAP to know for sure.

How True Is It That Plan B Can Mess Up Your Cycle

29 Oct 2013 by monkey1026
plan b, sex, period, unprotected sex

I had unprotected sex on the 15 . Neither I or my boyfriend was sure if he pulled out on time so we got plan b the next day . I heard I didn’t need it because my period been off and had two more weeks until my next one. My period comes the 26 I’ve been having all the symptoms of my period coming but it 3 days late. Can I be pregnant ? I’ve read the plan be can cause your cycle to change causing it to be a week late or early . How true is that ?


Yes, Plan b can delay your cycle. If you are more than a week late, you should go ahead and test though. Plan b is only about 80% effective. Pulling out does zero to nothing to prevent pregnancy. DO NOT rely on your partner pulling out as a method of birth control as you will find yourself pregnant shortly. Men leak out sperm way before they ejaculate and they cannot feel and cannot control this leakage. If you truly want to be safe, you need to get yourself onto the Pill, Nuva Ring, an IUD or Depo-Provera-some reliable form of birth control. You can get this from your regular Dr or he may refer you to a gynecologist or you can go to a county clinic or Planned Parenthood etc. Anything between you and your Dr is confidential. If you ask your physician not to share information, they cannot tell your parents. You do not have to be any certain age to go to a county clinic or Planned Parenthood.


It Should Not Be Used As A Form Of Regular Contraception

The morning after pill should only be used as a last resort. Not only does it mess up your menstrual cycle but it can effect your hormones, which can make you seriously moody. Although the common myth that you can only take it three times isnt true, the more you take it the less effective it becomes. According to Dublin Well Woman Centre emergency contraception is a very safe form of medication, but it is not a substitute for being on a more long-term routine form of contraception, such as the oral contraceptive pill or mini-pill, patch, or injection.

After Taking It You’ll Probably Experience Side Effects

“Some women experience nausea, vomiting, or headache while others experience no side effects at all,” says Metz.

“Breast tenderness , bloating, mood swings , sleepiness, and/or dizziness are common after taking emergency contraception,” Williams adds. “Another way to think about it is this: If a pregnancy occurs, progesterone is produced in the placenta and levels remain elevated throughout the pregnancyso, if you’re taking a progesterone pill, you’re getting all the symptoms of pregnancy.”

Ec Treatment Cycle Characteristics

Data on the characteristics of the EC treatment cycle are available for 232 women. Cycle length during the treatment cycle was shortened by two or more days for 49 participants and lengthened by two or more days for 57 participants . Cycle length was shortened by approximately one day for women who took EC in the pre-ovulatory phase of the cycle and was lengthened by close to two days for women who took EC in the post-ovulatory phase of the cycle, and these changes reached statistical significance . No difference in cycle length was observed for women who took EC right around the time of expected ovulation. Menstrual period duration did not change with pre-ovulatory EC intake but increased significantly with peri- or post-ovulatory intake. Estimated blood loss was equal to baseline in 68.5% of participants . Regression models showed that young women and women with short cycle lengths at baseline experienced significantly lengthened cycles after EC treatment .

Plan B Side Effects You Should Know About

Nauseous? Totally normal.

So the condom broke and you’re not on the Pill. Your move: Run out to CVS and pick up some Plan B.

But if you’ve never taken emergency contraception before, you might be wondering: Does this stuff have any side effects?

Plan B contains a type of progesterone, the same steroid hormone thats in oral contraceptives, but at a higher dose, says Iffath Hoskins, M.D., clinical associate professor in the department of obstetrics and gynecology at NYU Langone Health. It works by one or all of the following ways: delaying ovulation, preventing fertilization, and/or preventing egg implantation.

Though Plan B is generally considered very safe , that high dose of progesterone may cause a few potential side effects.

Here’s are the Plan B side effects you should know about:

Taking Plan B can cause your period to be lighter or heavier, or arrive earlier or come late. These side effects are due to the high-dose progesterone acting on the lining of the uterus at variable points in time during the menstrual cycle, says Hoskins.

How it affects your cycle depends on where exactly you are in your cycle when you take it. And while it may cause changes, these are always temporary, especially when the pill is used correctly, i.e. very rarely/occasionally and not regularly and repeatedly, she says.

Your next period should be normal, and come at the expected time, or within a week of the expected time.

Does Plan B mess up your cycle? For how long?

The morning-after pill is a good option for preventing unintended pregnancy, but its not your only one

By Flannery DeanJune 5, 2015

Plan B may be kept behind the counter at the pharmacy, but its reached the cultural mainstream of late. In a recent episode of Inside Amy Schumer, the comedian used it as a punchline in her hilarious Amy Schumer Doll skit.

Schumers joke suggests that Plan B is occasionally a Plan Abut in practice this is not a great idea, says Ashley Waddington, a contraception expert, OB-GYN and assistant professor of Obstetrics and Gynaecology at Queens University in Kingston, Ont. I worry if people are using it that way that they think its more effective than it is.

A lack of understanding about the way Plan B works may also result in the very thing women are aiming for it to prevent: unintended pregnancy.

Here are five things you need to know about the morning-after pill right now.

1. How it works Plan B is a hormone-based form of emergency contraception. Think of it like the birth control pill, only stronger. Its the same hormone thats used in the pill essentially, but in a higher dose, explains Waddington.

It works by pressing pause on ovulation, delaying the release of an egg from the ovary . Contrary to popular belief, however, Plan B doesnt generally stop a fertilized egg from attaching to the uterine wall. If the egg has left the chamber, so to speak, youre playing Reproductive Roulette.

What Happens After I Take It

Side effects of taking Plan B are generally mild and can include:

  • Headache
  • Abdominal pain
  • Occasional spotting for 1-3 days

If side effects are severe or you are having an allergic reaction seek medical attention immediately.

Your period should start within 21 days after taking Plan B. If your period is late by more than 1 week, pregnancy testing and follow-up with your health care provider are recommended. Plan B will not prevent pregnancy from future acts of unprotected intercourse, so use birth control until your next period.

How Often Can I Take It

You can take Plan B as often as you need to, but the more you take it, the more likely you are to have spotting and menstrual irregularities. If you find yourself needing Plan B often, talk to your doctor about other methods of birth control that may be more effective.

Plan B doesnt cause miscarriage and isnt an abortion pill. You shouldnt have the type of heavy blood flow that contains large clots.

Your Endometrial Lining Might Change

Levonorgestrel may sound like the name of a spell, but it’s basically just a form or progestin . And progestin is a synthetic that acts similarly to the naturally-occurring progesterone .

” side effect of taking this progesterone hormone is that it may affect implantation, which is a bonus as an emergency contraceptive.”Dr. Sheila Loanzon, MD tells Bustle. This works because Plan B changes the lining of the endometrium, Dr. Loanzon says, which also contributes to preventing pregnancy.
