12 days late cycle day 42

I feel like I am losing my mind! All tests negative. No spotting at all or any usual period symptoms. Headache and mild cramps I have had for about two weeks on and off. Called my Dr and they said they aren’t concerned until I am three months late. No mention of a blood test to be sure I am not pregnant. Dh says I need a new Dr. but I am trying to patiently wait for either Af to just come already so we can try again or by some magic a positive plus. Has any experienced this before or any insight is appreciated!!
