confused .. help

So i ovulated on January 17 from both ovaries. I went and did a pregnancy test on 29 January BLOOD TEST and they told me it was negative. So i've had the same symptoms after i ovulated gassy, cramping but the day before i took the test boobs started hurting feeling full.

So here i am expecting my period when this gush of what's normally ovulation discharge comes out. This isnt normally what happens when i'm getting ready to start my cycle. Am i tripping or could the test have been wrong? I caught some of what didnt fall into the toilet.
