Is this Boa Gravid?

So im about to get a Nic Boa in a Trade. The person claims she is Gravid and about to Drop her litter. Is this what a Gravid boa looks like? Even though she is a Nic Boa she is 6 feet. Could it just be a Regular red tail He's trying to pass off as a Locality? Thanks

Here it is

Anyone?

Seems awfully low to the cloaca. They dont normally hold them that low during gestation. As far as it being a Nic, its very dark like one but wouldnt be able to tell by that pic. Need a body pic.

Need a picture of the whole Boa.
