Is this positive or not?? Help!

Hi ladies,

I'm super confused. I took a EPT test a few days ago in the AM and it looked like this. Is this a positive or not?? But then this morning took a first response and it was negative. AF is almost a week late and no signs of my usual PMS symptoms. My pregnancy symptoms are fatigue,food aversions,breast soreness and heaviness, increase in appetite and nausea. Please help!! Should I just go to the doctor and do the test?? I wanted to be sure I was pregnant or not before telling anyone. Thank you!!
