All contraceptive methods can stop you getting pregnant, but some have other benefits, too. Condoms can help prevent sexually transmitted infections (STIs), while the IUS (hormone-based coil) can give you lighter periods, or even stop periods altogether.
Condoms and contraceptive pills are just the start, and the options can seem overwhelming.
