Pregnant?

Patient: Hi, I have not had a period since January 14th. I only had very light brownish red spotting around February 14th for 2 days. I have been having nausea, slight cramps, off and on sore boobs,and a lot more discharge but i have taken 6 home pregnancy tests and 1 urine pregnancy test at my doctors but all came back negative. Could I still be pregnant?

Doctor:
