Am I Pregnant?

I've always been one known to overthink things, obsessing over what could go wrong rather than what could go right.
I've been called many things: downer, party pooper, pessimist.

Truthfully, I'm none of these things. I just like to think of all the possibilities, especially the bad ones, just to be prepared.

However, there is one thing that I did not properly think through, one decision which's possible outcomes I did not obsess over.

What is that decision?

The decision to have unprotected sex.
