Being HIV positive should not stop you having a baby. Many sero-different couples (where one partner is positive and the other is negative), have had healthy HIV negative babies.
Your second question was whether it is possible to have an HIV negative baby without passing HIV onto your your girlfriend or baby. The answer is yes. However, this will depend on a number of factors.
Firstly, you would have to on antiretroviral treatment (ART) with an undetectable viral load. Are you taking treatment?
Secondly, both of you should be checked for STIs (Sexually Transmitted infections). This is good practice whenever two people are planning a pregnancy. STIs can sometimes increase the risk of passing on HIV to your negative partner.
Thirdly, the chance of conceiving is highest when your girlfriend is ovulating. Ovulation takes place in the middle of the woman’s monthly cycle. This is about 14 days before her period.
This link the the pregancny guide to is about how sero-different couples can conceive naturally. The guide also lists other conception options.
You may also find it useful to read the Swiss Statement. This describes the transmission risk for someone who is on stable HIV treatment as ‘negligible’ and ‘similar to risks of daily life’. It is difficult to put a percentage risk on this.
When you and your girlfriend decide you are ready to have a baby, you should speak to your doctor who will be to advise and assist you accordingly.
Good luck with your plans.
