Pink Dot

A pink dot on my pregnancy test?

I took a test and instead of a line there was a light pink dot? It was right in the middle of where the line should be. Does that mean there just isn't enough hormone built up? Has anyone experience this? I plan on taking another one in the morning.
It was the kind that you put a couple drops into the hole.

I would take another one first thing in the morning. But it sounds like a positive.
