Early pregnancy symptom?

So I might just be grasping at straws here but I didn’t pay attention this closely with my first pregnancy. What were your earliest symptoms before missing AF? I feel full all the time the last couple of days. Like I’m hungry but I still feel full if that makes any sense. I googled it. (Oops my bad) and it said that is a super early symptom but idk. Have any of you had this happen? I’m only 8DPO so I doubt it but I wanna get your takes on if this was a symptom or not.
