Has anyone had no period symptoms as their first symptom of pregnancy?

I get horrible periods, bad cramps and moodiness the week before and through my period. Those horrible cramps are my first reminder to stock my purse with tampons and check this app to see what day it’s expected to start. Well I haven’t had any cramps at all so I checked this app and my period is in a couple days. Well This is way out of the usual for me to have no premenstrual symptoms. Has anyone had no symptoms as their first indication that they are pregnant?
