Hi I Am Concerned I Might Be Pregnant. I Had

Hi I am concerned I might be pregnant. I had two short periods in August and September, each lasting a few days. Then September 18th was my last period. Me and my boyfriend had fooled around, I can't remember if we went all the way or not. Around August I started sweating profusely, got dizzy and nauseated, chest discomfort, etc. The next month the dizziness and nausea continued, and I started puking a little acid in my mouth from time to time, but swallowing it. I took two home pregnancy tests today which both came out negative. I went to a doctor and got blood work but I don't want to wait till morning to be sure. Is there anyone who can help me?
