The mini-pill can be obtained from your doctor, who will discuss the different types available and which will suit you best. An injection of a hormone called DMPA provides contraception for 12 weeks. The hormone is released gradually and prevents ovulation. It has the advantage that no further contraception needs to be used until the next injection is due. It can stop the periods altogether, which some women like, and it may help to prevent cancer of the womb.
Some women find that they put on weight.
The injection may take up to a year to wear off completely, so it is not suitable for women who plan to become pregnant in the near future. Your doctor will be able to advise whether this type of contraception will suit you. They release a progestogen hormone that prevents ovulation. They may cause irregular periods at first and sometimes they are difficult to remove. Implants are prescribed and fitted by your doctor.
