3 days late no sign of period but neg test?

So I'm 3 days late as of today, and so far I've taken one test day of missed period that was negative (but took it almost end of day) and I took one this morning. These are the pictures. However, I have no sign of my period coming! I've had slight cramps mostly on one side and nausea but other than that nothing. Should I use a different test and retest in a few days? Or am I out for this month. And these were taken in the 2-3 minute time.
