8 Days late and BFN.....anyone else?

I was pregnant in June and lost the baby September 11th when I had a D&C, my levels went to zero end of September, my cycle got back around November. I'm 8 days late this month. Took a test today and got a BFN, today my boobs are so sore I could barely put a bra on which isn't a normal period sign for me. I have been super exhausted, extreme migraines, lower back pains, vivid dreams and nightmares every night, spotted almost 3 weeks ago in between my cycle that only lasted 2 hours, today had a little cramping in lower abdomen, and mood swings. Last time my levels weren't high but didn't test until about 2 weeks past my period. Not sure if I am or not. Anyone else in the same boat?
