^yeah, but on the pixiv page there's a tag that reads ただの肥満 "it's just fat". And the 授かった(conceived, blessed [with a baby]) left radical is greyed out do it says 受かった (passed [an examination, etc.]). The character 受 implies "receive, incur" but 受かる only means to pass an exam, etc., and I don't know enough about the context to guess at what it means here.
I like to imagine it that way though, stuff/preg, either or. 'cos this artist usually does preg stuff.
