English: A birth control pill is a hormone-based contraceptive pill that can contain either oestrogen and progestogen, or only progestogen. These hormones prevent ovulation, which decreases the risk of becoming pregnant. You take one pill every day for about three weeks and then take placebo pills that don’t contain any hormones for a couple of days (the amount of placebo pills differ between different brands) to get your period. When there are no more placebo pills, you start taking the pills with hormones again. There are many different pills available, all with different amounts of hormones and other variations. In order get a prescription and figure out which pill works best for you, you need to contact a Youth Guidance Centre (ungdomsmottagning in Swedish), a Sesam centre, a midwifery centre or a gynecology clinic.
