Need some advice!!

I'm two days late for af. My period is normally on time. I had cramping Thursday night ( night before I was due) and then nothing. I normally have cramping for a few days before I'm due and I didn't this time. Today when I woke up, I noticed my nipples were really tender which normally doesn't happen. Is it possible I'm pregnant or am I just jumping to conclusions? I'm scared to test yet because I don't wanna see another bfn :-\ I have been under some stress but nothing too big. Anyone have any advice to help ease my mind?
