Pregnant w/ barely any symptoms?

So eve is estimating my period is about 20-21 days late. I have 5 days left of this month to get my period. I have had a little cramping that made me think I was getting my period but nothing yet. No other symptoms of pregnancy I can detect though...so I’m wondering if I am just having my hopes set too high or if I really could be and not notice any symptoms? How many of y’all found out y’all were pregnant with literally just a late period as a clue and nothing else?
