Confused

It’s been two weeks and still nothing. I’ve taken multiple tests and still nothing. Did a blood work exactly on the date it hit one week but blood work shows nothing. Been having sleepless nights. Body aches, headaches, feeling exhausted and tired all the damn time. What is this? I’ve been avoiding any medication or doing anything or lifting anything heavy. I never missed my period for this long. The last time I missed it for 8 days was last year and after I explained to my doctor I was told it was a miscarriage. I’m so confused what this could be. Has anyone gone through this?
