Princess Luna goes into labor during a bedroom encounter with you.
 
 
I could only call for the royal midwives unless Luna uses the Traditional Royal Canterlot Voice to do so. Otherwise, just try to keep her as calm as possible, taking deep breaths.

“Cheerilee goes into labor during a bedroom encounter with you.”  
I could provide emotional support, but other than that, I’d be just about useless in that situation.  
Though I suppose that’s still more useful than some husbands and baby-daddies are to their wives and baby-mommas while in labor.  
Also, June 1st wouldn’t make a whole lot of sense.

Nurse Redheart goes into labour while having a bedroom encounter with me. At least she has the right occupation to get through it!

So Cheerilee and I go into hiding as every other mare goes into heat.
 
Hope she likes playing Rimworld and EUIV…

Cloudchaser.  
Out of all the pegasi, Cloudchaser.  
Dust, jah, that arrogant imbecile.  
Flitter, jah, magnificent little bastard.  
All the others JAH JAH JAH JAH JAH.  
But Cloudchaser. I’ve placed my doubts right.  
Rarity’s been cheating on me for her;  
And even got PREGNANT!  
This is beyond my limits!  
Bring me Fegelein.

The End wasn't The End - Found a new home after the great exodus of 2012

Me: If you ladies will excuse me, I’m going to dig my own grave.
 
Twilight: That bad, huh?
 
Me: I got you and your foalsitter pregnant, not to mention that she’s MARRIED to your Brother. There’s no way I’m going to survive him when he finds out his wife and his LSBFF SLEPT with me.
 
Twilight: Logic aside, what about our kid!?!

Applejack returned from a long absence carrying my future children? Seems suspect but she is the element of honesty…screw it I’ll take my chances with her.

“After months of searching, you find Rainbow Dash in an isolated cottage surrounded by foals and expecting more” I suppose all of these would suck though (looks at other possibilities)
 
Eeyup. I was screwed no matter what.

I got a half-human foal with Derpy.  
Could’ve been worse.

Whatever bird that's dumber than a duck. Imagine I made the effort to research that and make a new badge for it. - Either a complete retard or a full time moron, it's hard to tell which and frankly I don't care either way
