Anyone get symptoms at 1 week?

Too soon to test, but I'm not feeling normal.

I came home today from and cried because dinner wasn't ready. CRIED!

My breasts hurt, my back aches, I'm tired and I'm cramping. Not to mention a bad case of the ugly cries.

We had intercourse last Friday and according to glow it was a 20% day. I have 2 children already and I don't honesty remember the beginning of either pregnancy. Anyone have any similar experiences in your pregnancy? Or am I going nutty?

Btw, when's the soonest you can test?
