My first tww and some of my back story

I started my first tww after my first month of ttc. How do you all handle the anticipation? Does anything make it easier? This will be our second child. Our 3rd if you count his that he doesn't get to see. Neither one of us had planned our first ones. This will be our first biological child together. I started cramping right away. I am currently 3 dpo and I feel like I'm crazy. But you know how a woman just knows she's pregnant, I feel that way now. Any tips on how to make the wait easier, and rather I'm crazy or not for already feeling pregnant?
