Pregnancy question?

For those of you who have been pregnant- how were you feeling before you knew that you were? My period is 8 days late now. It’s been this late before but this time I just feel really off. I can’t get the thought of the possibility that I could be pregnant out of my head. I haven’t had discharge or anything so idk. I’ve been really stressed lately so that could be it. But just wondering how you guys felt before knowing?
