Early pregnancy symptoms?!

I think I’m out for this month (period due in 2 days) but for future reference, what are some signs that could be telling I’m pregnant before a missed period? My typical tww goes like this: boobs start being tender around 1-4dpo, peaking in soreness around 8-9dpo, nausea around 6,7,8dpo, moody, hungry, you know - typical progesterone symptoms. Around 12dpo the boob tenderness starts to go away slowly until AF comes. If I was pregnant, would anything be different? Would my boobs not stop hurting? Or can progesterone lower before it spikes again once hcg is higher?
