I have no idea what this is or whether this tumblr made it, but it is absolutely fascinating, and I'd like to know who the artist is.
My impression is that it's abortion related. It makes me think of women who get pregnant after an abortion in order to conceive of a redeemer child who makes up for the one who was aborted. Like a blood stain, the memory of abortion is difficult to erase.
I like this a lot.
