Pregnant?

I'm thinking there is a slight chance I might be pregnant. My daughter is 9, and this is something I've wanted a second baby since she was 2. I've been pregnant a couple times since then. Once fairly recently. But my boobs are crazy sore, I think they may even look bigger. My moods go from 0-10 in like 3 seconds. I don't really "feel" pregnant. I don't want get my hopes up, and I don't want to get excited. It's too soon to take a test so I'm so lost.
