Welcome to HCM.
Nearly 30 to 40 % of the couple remain sero-discordant in spite of their continuous sex contact among the people living with HIV
. Various factors like absence of STD
, Roomy vagina, lubrication and absence of certain receptor sites in vaginal epithelium etc. are said to be contributory. At the same time, there is every possibility for you are in a very early infected stage (window period) and the sero-conversion may take time.
Immediately try to adhere strictly protected sex here afterwards.Even if you become reactive, protected sex is a must to prevent the early progression of the disease.
There is nothing to worry even if you become positive for HIV. It is just like any other disease. There are wonderful treatment modalities are available for HIV to keep under well control and you can lead a very comfortable and decent life without any problem for more than 30 years with available drugs. Meanwhile a drug to eliminate the disease totally also on the way.
So be cheerful.
Wish you good luck
