She doesn't look gravid to me, although I could be wrong (nearly impossible to tell for sure without seeing her in person and even then it can be hard). But usually gravid boas are quite distended in the lower 2/3 of the body - they will look more swollen there than overall thick like this. She does, however, look overweight. How often are you feeding her and what is the typical size prey she takes? How long have you had her and, if she was a more recent acquisition, was she this large when you first got her?
