Outlook Prognosis Serious symptoms are very unlikely. If you don't know which ones are the dummy pills, read the instructions on the accompanying leaflet carefully. If you're still unsure, check with your GP or pharmacist. This is when the mix of hormones in each pill is different, depending on which phase you're in.
The packets are usually split into two or three different coloured sections. Phasic pills need to be taken in the correct order to provide effective contraception. Check with your GP or pharmacist which pills you can safely miss out to delay your period. The progestogen-only contraceptive pill is taken every day, and your periods may be regular, irregular or have stopped altogether.
You can't delay your period by changing how you take these pills. If you're not sure what type of pill you're taking, always check with your GP or pharmacist before taking two packets back-to-back. If necessary, you can take up to three packets of pills back-to-back, but speak to your GP first.
The lining of your womb continues to build up as you take the pills and you may experience side effects, such as:. When you take two or more medicines at the same time, the effects of one medicine can be altered by the other s. This is known as an interaction. If this happens, you'll need to use extra contraception to avoid getting pregnant such as condoms , change to a different method of contraception, or take your contraception in a different way.
Some hormonal contraceptives may change the effect of other medicines, such as the epilepsy treatment lamotrigine and the immunosuppressant drug ciclosporin. You may be advised to change how you take the medication or to use a different method of contraception. The patient information leaflet that comes with medicines may advise that the medicine cannot be used with certain types of contraception. This information may be different from evidence-based guidelines used by health professionals.
If you're not sure whether your contraception interacts with other medicines, speak to your GP or pharmacist, or call NHS If diarrhoea occurs as a side effect of a medicine, it could affect absorption of the combined pill or progestogen-only pill.
An example of this is the weight loss drug orlistat. Other medicines can affect the hormones in the contraceptive pill if taken at the same time. This can happen with, for example, bile acid sequestrant drugs, such as cholestyramine. There are certain types of medicine that can increase the enzymes in your body.
This is known as being "enzyme-inducing". This can affect hormonal contraception, including:. Enzyme-inducing medicines speed up the processing of some contraceptive hormones and therefore reduce the levels of these hormones in your bloodstream.
This makes the contraceptive less effective. Enzyme-inducing drugs that can affect hormonal contraception include:. If you need to start taking another medicine while you're using hormonal contraception, make sure your GP or pharmacist knows that you are using this type of contraception. They can advise you on whether the other medicine will make your contraception less effective.
Your GP or nurse may advise you to use an alternative or additional form of contraception while taking another medicine. If you become pregnant while taking hormonal contraception, it will not usually affect your health or that of your baby. But you should tell your GP if you think you may be pregnant. Hormonal methods of contraception, such as the contraceptive pill , contraceptive implants and injections , contain the hormones oestrogen and progestogen.
They work by changing a woman's hormone balance. However, these hormones will not affect the result of a pregnancy test because they are not used to measure whether or not you are pregnant. A pregnancy test only reacts to the pregnancy hormone human chorionic gonadotropin HCG.
However, if you are pregnant, this hormone will not be present in your urine or blood until 13 to 16 days after ovulation the release of an egg , which is around the time that you would normally get your period. Until this time has passed it will not be possible to see a positive result in a pregnancy test. Urine tests require a certain level of HCG to be present in order to indicate a positive pregnancy result.
Birth control pills are 99 percent effective when taken correctly. That means taking the pill at the same time every day and following all other instructions provided by your doctor. In reality, with typical use, the average effectiveness is closer to 91 percent.
Still, some women may experience side effects from birth control pills. This is especially true in the first weeks after starting the pill. How likely you are to experience these symptoms depends on how sensitive you are to the synthetic estrogen or progestin in your birth control pill.
There are many brands out there, and each brand has slightly different types and doses of these hormones. If you seem to be experiencing side effects that are affecting your quality of life, another type of birth control pill may work better for you.
Sasan estimates that fewer than 1 percent of women on the pill will experience nausea from it. Instead, she says nausea is most likely due to missing a pill and having to take two or more pills in the same day. Women new to taking the pill could also be more at risk for nausea. Did you just start taking the pill within the past month or two? If so, your nausea may be related. Still, you should rule out other options, such as a virus or another illness, before assuming your birth control is causing your vomiting.
Though nausea has been known to happen with birth control users, Ross says vomiting is less likely to occur as a result. If you find that vomiting after ingesting birth control is becoming routine, you should schedule an appointment with your doctor.
First you should rule out other medical problems, such as the stomach flu. Shop for condoms. If you believe your birth control pill is causing your nausea, try taking the pill with a meal.
Taking it at bedtime may also help. Your doctor will be able to help you determine if there are better options for you.
