one week late!

So I’ve been late before, but not for a while. The past 6 months or so it’s been pretty spot on regular, typically a 29-31 day cycle. So now we’re a week past that mark, but idk if I should take a test yet. I’ve had tender breasts and was pretty moody for a few days, but I usually feel that way a few days before my period. But it never came. Then this morning I had cramps but still no period, and a bit of nausea, but I didn’t get sick.

Should I take a test or keep waiting it out?
