What is happening??? Am I crazy??

Ok, I'm 12 dpo. I took a first response with fmu this morning and got a vvf positive. I took a clear blue (not the digital) at 5 and got a negative...what the hell??? I was so excited especially after I posted my first test and ppl said it was positive but then took the clear blue and am so upset. Can anyone help me? 
Please help!
