Oral contraceptives (pill)
There are two types of oral contraceptives: the combined pill and the progestogen only pill (POP). They're 99% effective if taken correctly, but don't protect against sexually transmitted infections, so it is best to use both the pill and condoms if there's any risk.
Many women initially take the pill specifically to help with period problems, whilst others find their period symptoms (such as heavy bleeding, pain and premenstrual tension) improve as a result of being on the pill (see 'Living with periods'), and skin problems like acne can be relieved.
Women like the pill because it's easy to use, reliable, is under their control and can help make their periods regular. They also say it shows a responsible attitude to contraception and means that sex can be more spontaneous.
Side effects can include feeling hungry all the time, weight gain, going off sex, erratic bleeding, headaches, breast tenderness, feeling bloated, and mood swings. It's usually possible to find a pill that suits, although you may have to try a few brands before you get the right one for you.
The pill isn't right for everyone and can cause migraines, high blood pressure or even having to go to hospital if blood clots are suspected.
Some women stop taking the pill due to worries over the side effects of taking hormones or weren't very good at remembering to take it every day - in which case they often switched to Depo Provera injections (see 'Injections and implants').
There are pros and cons of taking the pill, and some women had been put off by friends and family, or had read negative stories in the media. Some really do not like the idea of taking hormones, although many feel that it's better to take the pill than risk an unwanted pregnancy.
One said that she understands why clinics have 'a bit of an agenda' but feels that women are sometimes under pressure to go on the pill.
Frequently women find men don't know much about the pill and some women wish they'd learn more, or even educate their partners themselves.
For women who find it difficult to swallow pills or have sensitive stomachs there are two other forms of contraception available that are based on the same hormones as the pill;
Evra is a contraceptive patch and
NuvaRing delivers the pill homones vaginally.
