It's likely you are at risk.

From the information you’ve given us about ther kind of sex you've had, and who you've had it with, it seems likely you've come into contact with HIV.

What to do now

When people have been put at risk of HIV there's a treatment called PEP that may prevent HIV infection after the virus has entered the body:

PEP stands for Post Exposure Prophylaxis
It involves taking anti-HIV drugs for 4 weeks
It must be started as soon as possible after unsafe sex or a condom not working – ideally within 24 hours but definitely within 72 hours (3 days)
There can be side effects such as diarrhoea, nausea and prolonged headaches
PEP isn’t guaranteed to work

As your risk happened over 72 hours ago, you should talk to a sexual health clinic or hospital accident and emergency department as soon as possible about what they recommend you do next. They might feel it's too late for PEP but they will be able to advise you about getting an HIV test.

You will need to explain to the doctor when and how you were at risk and any other relevant information (eg. your partner’s HIV status, the type of sex you had etc).

PEP is not a cure for HIV and is not guaranteed to prevent HIV from taking hold once the virus has entered the body. Condoms and lube for sex remain the most efficient way of preventing the spread of HIV.

If you can't get PEP

If you can't get PEP it's important to remember that even though you have been at risk of HIV it doesn't mean that transmission has occurred.

The only way to know this for sure is to take an HIV test. We recommend talking to someone at the hospital or clinic about getting tested.

If you do have HIV, it's far better to know as treatment means you can expect to live a long and healthy life, whereas if you don't treat HIV it's likely you'll become ill.

Also, if you have been at risk from HIV, there is a chance you may have picked up other infections as well. You can be checked for these confidentially at any sexual health clinic.
