Being HIV positive should not stop you having a baby. Many sero-different couples like you (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 be stable on ARVs (antiretroviral treatment for HIV) and with an undetectable viral load. Are you taking treatment?
Secondly, both of you should be without STIs (Sexually Transmitted infections). STIs increase the risk of passing on HIV to your negative partner.
Thirdly, unprotected sex should happen only when your girlfriend is ovulating. This will increase the chances of your girlfriend getting pregnant without becoming positive herself. (Ovulation takes place in the middle of her monthly cycle, about 14 days before her period.)
Please follow this link to our guide to how sero-different couples couples like you can conceive naturally. The guide also lists other conception options available to you.
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 future plans.
