First pregnancy symptoms?

What pregnancy symptoms did you experience before finding out you were pregnant? I have had sore boobs for 6 days, I have been having hot flashes and getting hot and sweating easier, I've been peeing in the middle of the night which I usually don't do, and I just kind of "feel" pregnant. Also, last night my boobs felt really heavy when I took my bra off. I am waiting until Friday to take an hpt :)
