No symptoms a week before af....Pregnant?

Katie • Hi my name is Katie! Im 25 and my husband is 24. We will be married for 4 years in October. We our currently ttc our 1st child and are very excited!!!
I was wondering if anyone has ever gotten a BFP with out having any symptoms at all? My af is due tomorrow and usually I'll have cramps the day before and my breast will hurt for the few days before as well but so far I've had nothing at all. During the first week of my tww I had a couple light cramps through out and a little heartburn. Any opinions or similar stories?
