What's the very earliest symptom of pregnancy you have had?

Last time I was pregnant was five years ago at 19 and it ended in miscarriage.. I knew I was pregnant because my breasts were so sore I cried after running up a flight of stairs but now I'm ttc I'm mistaking all period symptoms for pregnancy. AF isn't due for nine days but I noticed a change in discharge (thick/creamy/white), sickness, fatigue, sore breasts, cramps on one side ect so thought I'd ask everyone what their earliest symptom was.....
