Tww - My First Two Week Wait!!!

This is my first TWW! I am so nervous, been wondering if anything I'm feeling could be pregnancy related (it can't because I'm only 3-4 days DPO). I'm so scared we didn't make it, I'm scared we didn't conceive. I don't want the heartbreak that comes with infertility, my heart aches for women who suffer it. My family is generally super fertile but I know that isn't a predictor of my fertility. We shall see...share your stories with me, are you DPO? What are you feeling?
