Congratulations! It is possible to have light periods throughout a pregnancy (which is part of why some women never know they're pregnant until they deliver. My firiend's sister was anorexic and didn't know she was pregnant until 7 months in. She went in to hospital to be scanned for a suspected ovarian cyst. Man. Head Asplode. Although being anorexic, she might have NEVER got periods, and that's why she didn't know.)
I don't think that reverance or respect for the dead needs the dead to be hidden from sight completely. It is the attitude that you bring, as a witness to a dead body, that matters, not the display and witnessing of a dead body, per se.
