It seems like this song is about having a miscarriage. "Nobody knows your name, it's easier" refers to the fact that she probably had a name in mind that she never told anyone, because it probably happened relatively early in the pregnancy (a lot of women wait awhile before telling people about their pregnancy just to make sure everything goes ok). "Finally you can breathe" - the baby went to heaven and now has a "life" I guess, since it never had the opportunity to live outside of the womb. "Clench your fists till they almost bleed" - the woman is angry at herself for being an inadequate mother. Also, when I think of babies and ultrasounds I think of tiny fists and fingers. "Your mind is swollen from months of thought without release" - during the months of her pregnancy, she was anticipating the birth of her child, but there was no release of those feelings of anticipation because it never came. Not really sure about the rest of the second verse or the chorus. The color scarlet is suggestive of reproduction. This is just one interpretation, I'm not saying it's right or wrong (there is no right or wrong answer).
