Missed period negative test

So my last period was March 9th and I track my period every cycle and its very regular. I have done multiple test and it’s negative like a clear negative. So I am not worried about that would you be concerned? I have never missed a period other then when I was pregnant. Would you talk to the doctor about it or wait another month? Is there anything they can even do? I feel awful my body feels bloated and not good. Also I am a little stressed because I don’t understand? I have changed nothibng. I do jog a lot everyday around 12km minimum could that be affecting it? But I have for the last 2years and it has never not come.
