stomachs are very usual in new-borns. Without someone (who would know what they are doing - probably not me) doing a post-mortum dissection within minutes of death, there is no way of knowing whether the red indicated birth defects, internal bleeding, parasites, a bacterial infection or something else.
A pretty standard question at this stage of the game is to ask if you moved the late term female within the last week. Many times we get away with that, but too often there is a premature drop or other complication.
You told us little about your tank in terms of its temperature, filtration, tankmates, how many weeks you have been waiting (this asked by a guy who sits in front of a microwave and screams "FASTER") and much more. Take a look at the 40 questions in

and see if answering any of them is possible.
By the bye. I understand that we seldom are going to read a site's rules and FAQs when we are preoccupied with an immediate issue in our aquarium. But you will often get a quicker response if you post a relatively short question as a diary. More people will see it sooner.
I'll vote you your "mulligan" this time. But a several hundred word Log submission is often too short to be a real log. ;)
Give your female guppy all of the TLC you can. Hopefully she will be able to deliver healthy fry next time. If you offer some specifics on the tank and care, maybe more specific suggestions can be made. :)
Good luck and all the best!
