This used to be more of an issue when we understood less about the link between viral load and infectiousness.We now know that if you’re taking HIV medication and have an undetectable viral load, you cannot pass on HIV.Your girlfriend may also find it helpful to read the guide as it answers a lot of general questions around HIV and pregnancy.

But anyways, I’ve grown to love and want a future with her. Can you please confirm whether you were referring to her CD4 count or her viral load. The aim of treatment is to get the viral load to undetectable (below 50 copies).

You mention in your question that your girlfriend’s count is low. If someone is on treatment, viral load tests also show how well the treatment is working.

HIV treatment - used by HIV positive and negative people - is also a form of protection.

However, before deciding to stop using condoms, it’s a good idea to speak to your HIV doctor or nurse to make sure your viral load is undetectable.

If you have a detectable viral load, have unprotected sex and don’t tell your partner they may be angry that they weren’t told sooner.

If a partner is not told and they subsequently contract HIV as a result of having unprotected sex you could be prosecuted.

It’s also important to remember that if you have sex without a condom other sexually transmitted infections (STIs) can be passed on.

Remember, sex without a condom can also lead to an unplanned pregnancy if other contraception is not being used.

Ovulation takes place in the middle of her monthly cycle, about 14 days before her period.
