Do Low Doses Of Birth Control Prevent Pregnancy

When Should Emergency Contraception Be Used

Should I take a low dose birth control pill during perimenopause?

Emergency contraception should be used after unprotected sex, or when another birth control method, like condoms, failed or were used incorrectly. Its generally advised to take a morning after pill as soon as you can after sex. You can take a levonorgestrel up to five days after unprotected sex, however the longer you wait, the less effective it becomes.

Although levonorgestrel morning after pills are the most common in America, if youre over 155 pounds, you may be advised to try another option like ella . This is a prescription only option however, and may make your hormonal birth control ineffective. In some cases, your doctor may recommend a copper IUD, which can then also be used going forward as an effective birth control method.

  • ask a GP, practice nurse or pharmacist
  • read the patient information leaflet that comes with your medicine

Antibiotics

The antibiotics rifampicin and rifabutin can reduce the effectiveness of the combined pill. Other antibiotics do not have this effect.

If you are prescribed rifampicin or rifabutin, you may be advised to change to an alternative contraceptive. If not, you will need to use additional contraception while taking the antibiotic and for a short time after. Speak to a doctor or nurse for advice.

Epilepsy and HIV medicines, and St John’s wort

The combined pill can interact with medicines called enzyme inducers. These speed up the breakdown of hormones by your liver, reducing the effectiveness of the pill.

Examples of enzyme inducers are:

  • the epilepsy drugs carbamazepine, oxcarbazepine, phenytoin, phenobarbital, primidone and topiramate
  • St John’s wort
  • antiretroviral medicines used to treat HIV

A GP or nurse may advise you to use an alternative or additional form of contraception while taking any of these medicines.

Birth Control Pills Today

There are now more than 200 brands and varieties of progestin/estrogen birth control pills on the market. All of them from Alesse to Zovia sometimes prevent implantation of the developing human being. The low-dose pills work in essentially the same manner as the old high-dose pill. However, a much higher percentage of ovulation occurs in women who use the low-dose pills due to their lower estrogen dose. This means that all of the newer oral contraceptive pills act as abortifacients at least part of the time.5

Women who use these pills thus frequently conceive. In order to prevent the continuation of pregnancies in these cases, the low-dose pills also prevent implantation, thereby acting as back-up abortifacients. Several studies have shown that women on the low-dose birth control pills experience an early silent abortion during a wide range of 2% to 65% of their cycles, depending upon the pill formulation used.6

The mechanisms of action of mini-pills are similar to that of the standard progestin/estrogen birth control pills.7 These progestin-only pills interfere with implantation by affecting the endometrium, thickening the cervical mucus, and suppressing ovulation in some women by reducing the presence of follicle-stimulating hormone .

Innovations in Contraception: Understanding Your Birth Control Options

Contraception services are free and confidential, including for people under the age of 16.

If you’re under 16 and want contraception, the doctor, nurse or pharmacist will not tell your parents as long as they believe you fully understand the information you’re given and your decisions.

Doctors and nurses work under strict guidelines when dealing with people under 16. They’ll encourage you to consider telling your parents, but they will not make you.

The only time that a professional might want to tell someone else is if they believe you’re at risk of harm, such as abuse. The risk would need to be serious, and they would usually discuss this with you first.

If You Missed 2 Or 3 Pills

If you missed more than one pill, or if its been more than 48 hours since you last took one, thats another story.

Youll definitely want to use an extra form of contraception as backup or avoid penis-in-vagina sex until youve taken hormonal pills for 7 consecutive days.

How you proceed after missing two or more pills in a row depends on where you are in your cycle.

If it happens during week 1 or 2:

  • Take the most recent pill you missed ASAP.
  • Throw away any other missed pills.
  • Keep taking the remaining pills in your pack as you normally would, even if it means taking two pills in 1 day.

If it happens during week 3:

  • Take the most recent pill you missed ASAP.
  • Throw away any other missed pills.
  • Finish the rest of the hormonal pills in your current pack then, skip the entire week of your hormone-free reminder pills and instead start a brand-new pack as soon as possible

Occasionally forgetting to take a birth control pill is one thing, but if it happens frequently, consider talking with a healthcare professional about other birth control methods that dont require as much consistency.

The following birth control methods can be used from once per week up to every few years:

Short answer: no. The mini pill is another form of oral contraceptive. Unlike low dose combination pills, mini-pills contain progestin only. There is no estrogen in them.

The primary way progestin only pills work is by thickening cervical mucus and thinning the uterine wall. Occasionally they prevent ovulation, according to the Mayo Clinic, but thats generally attributed to the estrogen in combination pills.

How Does The Birth Control Pill Work

Before one can fully appreciate what makes low-dose contraceptives different than other forms of birth control, its crucial to understand how the birth control pill works.The female reproductive system operates under a cycle of rising and falling estrogen, progesterone, and androgen hormones. At the beginning of the cycle, hormones steadily increase until the ovary is prompted to release an egg. Once this happens, hormones influence the uterus to grow an endometrial lining in preparation for a fertilized egg. If an egg is not fertilized within about 10 to 14 days after ovulation, the endometrium sheds, resulting in a menstrual period.

The pill disrupts the rising and falling of reproductive hormones by a steady dose of synthetic estrogen and progesterone. The endometrium is not signaled to grow to prepare a fertilized egg, and when women who take the pill have a menstrual period, its not really a period because ovulation did not occur. Monthly bleeding on the pill is referred to as withdrawal bleeding.

Naturally occurring estrogen in the female reproductive cycle is produced in the ovaries. Estrogen helps the uterus grow the lining that is responsible for the implantation of a fertilized egg.

How Birth Control Works

Birth control pills are comprised of two artificial hormones that are able to hinder ovulation progesterone and estrogen, according to healthywomen.org. The natural cycle of ovulation begins at the start of every menstrual cycle. First, estrogen levels increase for about 14 days and cause the walls of the uterus to thicken in order to be able to maintain the egg when it arrives. When estrogen levels reach its climax, the egg is released and sent to the uterus. The levels of the hormone progesterone rises, also thickening the lining of the uterus in preparation for when it becomes implanted. Essentially, birth control is able to maintain the hormones at a certain level in order to trick the body into not releasing a healthy egg to be fertilized. The consistent thick walls of the uterus prevent sperm from reaching the egg, as well.

The Birth Control Pill Has Serious Side Effects

The Searle Pharmaceutical Corporation developed Enovid, the first birth control pill, in the late 1950s.

Enovid and other high-dose pills have generally fallen out of favor in the United States. However, they are still used in some developing countries. They contain from 1 to 12 milligrams of progestin and/or 60 to 120 micrograms of estrogen, a natural female hormone. This high dosage had a variety of side effects, including blurred vision, nausea, weight gain, breast pain, cramping, irregular menstrual bleeding, headaches, and possibly breast cancer.

Beginning in about 1975, pill makers, reacting to extensive publicity about the severe side effects of the high-dosage pills, steadily decreased the content of estrogen and progestin in their products. However, the patient information pamphlets for the various brands of birth control continue to feature a long list of very serious side effects, including venous thromboembolism , stroke, hyperkalemia , carcinomas of the breasts and reproductive organs, liver disease, high blood pressure and gallbladder disease. They also list a host of less dangerous side effects, to include headaches and nausea, weight gain, back pain, bleeding irregularities, depression and breast tenderness, most of which have an incidence of between 8% and 33%.9
