Earliest pregnancy signs?

What were your earliest pregnancy signs and when (how soon)?

My last pregnancy (8 years ago), I knew 1 week before my missed period. My breasts were very tender/sore, more than they usually get before getting my period. I also got frequent migraines around that time.

My husband and I are trying for a baby and I'm curious to see what other mamas have experienced since it's been so long for me.
