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.
If you’re 13 to 16 and want contraception, an abortion or tests for sexually transmitted infections (STIs), the doctor, nurse or pharmacist won’t tell your parents (or carer) as long as they believe that you fully understand the information you’re given, and your decisions.
You don’t always notice symptoms if you have an STI. Many people don’t notice symptoms and most people with chlamydia have no symptoms. You won’t always know if you’ve got an STI and you can’t tell by looking if someone has one. Protect yourself by always using a condom. If you’re worried, visit your GP or sexual health clinic.
