CD 34 ... 4 Days late.

So... A week before AF was due I started having diarrhea. A couple days later it quit and ever since I have had cramping and white discharge...and a lot of it. I'm constantly running back and forth to the bathroom to see if I started. Yesterday I had flu like symptoms and cramps were worse and the cm was more heavy. Today I feel fine just a headache but bbs are very sore. Yesterday I decided to go on and test and a FAINT blue line showed while the test was still going. Picture was taken within 5 min of test. Today, I took a First Response and its Negative as can be. I have no idea what's going on ...
