I don't know what to think anymore...

I'm 10 days late. I've been for a blood test and i've done the urine test and they all negative yet i have most of the syptoms. )Vomitting, nausea, tender and swollen nipples, strong sense of smell, mood swing and cry at the stupidest thing. )

I've been of the pill now for four months could this all be a hormone thing or could i be pregnant?

Please can someone help me?
