Help! TTC wanting a positive!!

I ovulated on cd11 , my cycle normally is 28 days im due AF oct 3rd (which im praying she doesnt show) this was round 2 of 50 mg clomid and i started progestrone suppositories 5 days after ovulation. Anyways ive been nauseas and nipples and breast are sore but they both go on and off throughout the day. Im 5 days until AF and i tested today ( not first morning per) and it was negitive! :(( im wonderinf if i still could be pregnant just tested too early??? Thoughts?????
