Symptoms??

Okay this has been how my last two weeks have gone:

Cold/Flu like symptoms- I brushed it off as allergies or sinus infection

Occasional dizziness

Missed period- except for 3 days this week where I have had light brown spotting/discharge like cm in the morning but nothing else throughout the day

Middle of the night vomiting/nausea last night and nausea again this evening.

Insomnia and just haven't felt up to eating my favorite things lately...

Also some cramping. I'm 12 DPO so I know I should just test but I honestly don't want to get my hopes up... what do you ladies think?
