No signs of pregnancy or labor scene, so...

Francis Sparkle, you are not the father!

Pony pregnancies are undetectable with the human eye.

Wanna bet?
 

Would you really want to see Cadance pushing Flurry Heart out of her love tunnel? Besides: if you want to see a horse giving birth, there’s always youtube.

@Crystal Neighybánya  
Other cartoons did it (I mean labor scenes), so why not this one?

@Flaming Frets  
Because Hasbro censors, you dingus.

@MrXemnas1992  
What a bunch of cop-outs.

Who is Francis Sparkle?

@Flaming Frets  

 
Shining: Wait, you mean…I…YES! YE-HE-HE-ES! I’m off the hook now! HAHAHA! (jumps around the room with glee.) Ohhh, sweet relief-I’m not a daddy! Y’know, I think this calls for a personal celebration. (makes suitcase appear with magic.)  
Cadance: Umm, honey? What are you doing with that suitcase?  
Shining: (turns towards Cadance with dilated pupils.) I’m going back to Canterlot, baby, so I can return to my job as a royal guard…cuz she’s not my daughter! WOO! Have fun with your overpowered, big-eyed abomination! (runs out door, sound of a car racing away can be heard.)  
Cadance: (sigh) Why am I married to such a big moron?

@DaKurgan  
Ever seen Friendship is Witchcraft? (the episode “Foaly Matripony”, to be precise)

@MrXemnas1992  
too bad. princess cadance all fat and hormonal would have been comedy gold.

@Flaming Frets  
Would YOU want to deal with angry soccer moms, ultra-conservative Christian parents, OR Standards and Practices?
 
 
@DanielTepesKraus  
It would, but again… a pregnant pony would be difficult to show without getting into hot water.
 

 
@Flaming Frets  
>Friendship is Witchcraft  

@Flaming Frets  
Using a tryhard fanvid that’s clearly not meant to be taken seriously and using it to disprove to something happening in the show?
 

@DaKurgan  
But I don’t.

Maybe being born without the horn and growing it later would work…

I think it’s more likely the reason we never got a heavily pregnant Cadance is the expense of re-doing her Flash model rather than censorship. Still, I was hoping for at least a few episodes of Cadance getting sudden cravings for pickles and hay, needing to stop the train every ten minutes so she could go powder her nose, having ponies she doesn’t even know stop her to feel her belly without asking, etc.

@Ferrotter  
Pretty much this.
 
Jim Miller said at one of the cons that it would’ve taken too much time and resources to make big belly Cadance, and it would’ve looked weird.
