Am i preggers??

So I am going tomorrow to find out for sure but here's what happened. I took a first response and it came out negative. 4 days later I took a clear blue digital and it was positive, I took a clear blue pro (line test) and it was negative the next day. The following day I took a clear blue digital in the morning (positive) and a clear blue pro at night (negative). I have a few symptoms, nausea, fatigue and super emotional. My PMS symptoms are completely different I get pissy and crampy beyond belief.
