Is my guppy about to give birth? Or is she full of crap.

Here are pics of my guppy.

Is she close to giving birth or are the gravid spots I see just intestines full of fish waste? How does one tell the difference?
Sometimes she looks really round and full, but that could be from food... and sometimes the dark spot gets smaller and fainter. I got her at the LFS 6 days ago, so these are my observations so far.

Thanks!

I dont think she is "about" to give birth, but she is pregnant

She does not look ready to give birth yet. She will get much bigger.

Agreed she is pregnant but not ready yet. She will look as if she is about to burst when she is close, also her backside will square off a bit.
