Pregnant or no?

Lex

I got a positive ovulation test 6/29/2014. On 7/6/2014 I checked CM and it was super creamy looked like glue and was a white/yellow color. Right after I had slight spotting that only happened when I whiped that one time. I took a test yesterday 7/8 and it was negative. I've been so worn out, I feel like my body is breaking in half. I am so nauseas it's crazy. I really just need advice. 

​Did I test too soon? Or could it really be negative?  

Please help!
