This has nothing to do with nothing huh?

I'm currently 2 dpo.. I've had cramps these past two days ( 1dpo and 2dpo) . I am a teacher assistant at a middle school and the teacher told me today I wasnt myself. Then I started feeling different, like I've been drugged of something. I'm not sick or anything , she said I was just not as chipper as I normally am. I have somethings on my mind, but I'm always psyching myself out. I'm sure the cramps and feeling different has nothing to do with nothing huh ? I want to be pregnant so bad.

P.S. I'm not stressing over it. Im very confident we conceived this month. ( I've been putting it in the atmosphere all month , that its ours)
