Hi, You are lucky in that you are married to a husband who is HIV positive,you have a baby with him who is HIV negative and your self as negative,thank God for this because it is rear.
However this is possible and is called discondent where by one of the married courples is infected with HIV and the other one is not. This is possible because of the variation in blood groups.
Some people are said to have a special form of cells called T.cells these are very resistant to the virus which cause AIDs.However more research is being done about these cells called the T.cells
On the other hand your body survived not to have HIV because may be you gave birth from a Hospital where PMT CT is practised.
PMT CT Stands for prevention of mother to child transmission.
Take note that you need to be very careful because any time as you continue having unprotected sex with the same person,you may get infectected in the long run.
