Late period no pregnancy symptoms?

I was supposed to start my period on Sunday.. but it has yet to come. I started feeling like I was going to start about a week ago and every day I’ve had cramps like it was going to start, yet nothing.

I’m always on time! So it’s weird. I haven’t taken a pregnancy test because besides cramps I have zero other symptoms!

We use pull out method (for the past 3 years).
