You can get pregnant even if you are breastfeeding your baby, and before your periods have restarted. If you are having sex and you don’t want to get pregnant you should start using contraception from three weeks after your baby is born, even if you are breastfeeding.
If both partners have HIV, you should still use a condom. Evidence shows that there may be different strains of HIV. If you and your partner are both diagnosed with HIV it may not be the same strain, so condoms are important to prevent cross-infection and the passing of other sexually transmitted infections.
Condoms come in a range of sizes. If the condoms you’ve used were too small or big, look out for different sizes or ask your pharmacist or a doctor or nurse at a sexual health clinic for more information. If you’re not sure about the size, try one on alone before you have sex to see how it feels.
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.
