I can't wait

I keep testing early .... I have been dog tired over the last week not eating much but eating more when I am hungry....  Nauseous and a lot of discharge  I slept all day yesterday ( and I don't do naps) hot flashes (I'm only 28).. I have tested every day this week and I'm getting negatives .... Granted I'm only 7 days past ovulation.... Too early for blood work or wait it out ?
