Hep c....

I'm very sorry for asking this on this board, but I have no where else to go. We just found out my father in law has hepatitis c, and myself and my 6 year old son have been around him. I have not seen any blood from him noticeably but he is very old and dying of cancer so I have been helping him a little bit. My concern is, my mother and father in law took their RV to Florida and he was very sick laying in the bed a lot, and I allowed my son to sleep in that bed.. Not thinking that if he did bleed, it could live up to 6 weeks in the blood. Now I'm not even sure if he had bled in the bed, but my mother in law told me to quit blowing things out of proportion and that she washed the sheets. I have anxiety very bad and I'm worrying myself to death because I am 23, 33 weeks pregnant, with a 6 year old and I'm not sure if one of us could have it.
