Such a mess right now lol

My period is 18 days late, all HPTs were BFN. Went to doctor this past Friday, had a well woman's visit with Pap smear etc. they also did a blood test (I won't know results until tomorrow) and I had some spotting and cramping after the exam which he said is normal. But now I have a killlller migraine to the point that I feel sick to my stomach. I just want to know if I'm pregnant or not :(( being so inpatient right now lol
