Proof There Are Not Triplets in My Belly

I'm currently taking two yoga classes; one is a prenatal class and one is a regular level 1 -2 class. They're both great. I think the regular class must have secretly been a senior citizen class because every person in it is over 40, and then there's me, this young pregnant woman. Most people in the class know I'm pregnant because I had to tell the instructor (there are certain poses you can't do while pregnant, and being the good yogi I am I have no idea what all of them are) and a lot of people heard me tell her this. It actually went more like this:

Instructor: "Does anybody have anything that I should know about? (mostly looking for injuries)

Jenille: "Oh, yea, I'm pregnant"

Instructor: "Congratulations! How far along are you?"

Jenille: "17 weeks"

Instructor: "Great, there will be some things you can't do but I'll give you alternatives"

Jenille: "Great"

Couple People in Class (whispers): "She sure doesn't look like she's 17 weeks"

Jenille: "Looks at them like, I know what you just said"

And there's the proof that I cannot possibly have multiple babies inside of me.
