Where oh where is my period?

I am 4 days late on my period. My period normally last 5 days. I have not had my normal period symptoms. No cramps.

Instead I have had bad insomnia and I'm a little emotional. Not drastically so. (Ex: This morning my husband was going to get me coffee but then couldnt bc he didnt have time then right after that I couldn't find my make up thought I left it at work, I cried like a baby)

I took a test this morning and it was negative. And I see all these others that are getting bfp and test early.

I'm just upset and confused. I just either want a bfp or my period, and a full nights sleep.
