Can HIV be transmitted from a mother to her baby?
An HIV positive woman can transmit the virus to her baby during pregnancy, labour and delivery, and through breastfeeding. If she takes no preventive drugs and breastfeeds then the chance of her baby becoming infected is around 20-45%.
Can this risk be reduced?
Modern drugs are highly effective at preventing HIV transmission during pregnancy, labour and delivery. When combined with other interventions, including formula feeding, a complete course of treatment can cut the risk of transmission to below 2%. Even where resources are limited, a single dose of medicine given to mother and baby can cut the risk in half. AVERT is currently running a campaign to ensure that all women have access to these drugs.

I hope this helps ease a little anxiety. First and foremost, get yourself to an OB and start medications. As others have said, you have time to make a parenting or adoption plan. You have a lot of changes right now, treat yourself kindly!
