What do you suggest (super quick)

the thing is last 3 months of period on track and on time with glow. My period is 4 days late and no sign of period I feel as thought I am on my period because I have cramps like I usually also sore nipples as well. I took 4 test and all negative. How should I move forward I don’t want to buy a bunch of test I might order on amazon but I want to just got with I am not pregnant n have a late flight period because I think it would show up by now but I really have never experienced cramping with a late period and I just feel off.
