Nauseous

My fiancé and I had sex on a day I was 2.8 fertile, the past 8 days I have been very uncomfortably nauseous. Is there any possible way I could be pregnant? The date was November 3. I don't think it's possible but in the past I did start experiencing nausea a few weeks after my first pregnancy which I lost 3.5 months in. My diet hasn't changed and it happens worse when I lye down. Maybe I'm just sick. Any answers would be appreciated. We've been trying for 2.5 years and he just said "I hope your not pregnant". Really rubbed me the wrong way
