Thanks a lot for your comfort and information. Both my baby and I are very grateful for your kind words.
Yes, I think pregnancy brought me into a paranoid state. I always worry everything that might infect my baby. But I still got a little problem that I hope you can give me some hand on too.
To testify if the blood stain was dried or not, I also used some toilet paper to wipe it. Of course I didn't wear any gloves at that time. The blood stain seemed to be dried for I couldn't wipe it off with toilet paper. Unfortunately, I only washed my hands using cold water (no soap) for several seconds afterwards. Then I felt itchy on my arm due to a pimple, so I scratched it using the same hand with which I just held the paper to wipe the blood stain. Now I began to freak out because the pimple was broken. Do you think if the virus(if still active in the dried blood) could break through the several layers of toilet paper (unsoiled, dried paper) and get to my hand? Is there any possibility that hiv can be transmitted in this way? (by my dirty hand, first trying to wipe off the blood stain with toilet paper, and then scratching the pimple on the arm).
Thank you very much for your patience.
