Might be pregnant??

So I'm a little nervous that I might be pregnant...my husband and I are not ready for a baby even though I would love to have one! We had sex the day before I ovulated, it was our anniversary, and we didn't use any protection...he says he pulled out but I'm honestly not sure. Pretty sure he said that because he doesn't want me to get excited at the possibility. However, that was 2 weeks ago and I've been extremely nauseous for the past few days, feeling very bloated and very sensitive to smells, also getting little dizzy spells. I took a hpt and it was negative but my period isn't due for another 8 days and I honestly just feel pregnant..does that make sense? Help!!!
