was this positive? was this a C.P?

I took this about 13dpo and I had these faint lines prob 15 min after coming back to the tests. Last Friday and last Saturday. Wasn't sure if they were evap lines or the real thing. Anyhow... I started getting cramps on Sunday and later that night my period started. I'm pretty sure this was a chemical preg. But what do you think? Was I preg? Or am I just seeing evap?
