Of course I'm spotting

I don't know why I would expect to be pregant more than a week before something happened to make my heart skip a beat.

I'm spotting. Not red blood. Not a lot. But fuck.

I spotted during my first and most successful pregnancy (pathetic that I call it a success to have made it to 19 weeks)so logically I know that this most likely is nothing. But still, I'm scared.
