anyone?....help

So me and my boyfriend have sex like EVERYDAY. And I honestly love it, because I'm making him happy and pleasing him and myself. But recently I was cooking dinner and I love eggs, but that night I tried eating them and all I wanted to do was puke my brains out. The smell of them didn't help either. Then I would wake up some mornings and sometimes in the afternoons and feel very nauseous. I got to the point were I couldn't really eat. Abt three- four nights ago after we were at Taco Bell and I "thought" I was really hungry but once I got my food I felt really sick and couldn't even eat it. Then abt two-three days after my BF started throwing up out of nowhere one night and the next morning as well. His uncle made a comment that I must b pregnant and he's experiencing some of the sickness. I haven't taken a pregnancy test yet. I still have abt a good week until my period I believe. Idk when I should take one? Or if anyone else has went thru this at all?
