Could I be pregnant?

I’m having things that are symptoms of early pregnancy; nausea (but no vomiting), headaches, fainting, constipation, breakouts, shortness of breath, food and sometimes smell makes me nauseous, but I’ve taken two pregnancy tests and they were both negative. But my period isn’t supposed to come for about another week so it’s too early to tell if my period is late or not, does this possibly affect the result of the pregnancy test? Should I go have a blood test done.
