Pregnant... PLEASE read

My SO and I made sure to have sex everyday through my fertile window. I am 8 days before my period starts.. When is the earliest I can take a pregnancy test to know if I am or not? I have already been feeling weird and wanting things I wouldn't normally want. And after I eat somethin I feel sick.. So idk if that's just me or what.. Any advice or anything would be greatly appreciated .
