Got a home positive but a clinic negative

I posted the other day that I got a positive home test, faint but still positive. Today I went to a free clinic to confirm and it was negative. I don't know what to think. Am I pregnant or not? Was their test wrong or mine? I got two positives. They told me to come back next week if I still haven't had a period and retest. I just want a positive so bad.

This was my home test. Second test the next day with first pee.

This was the first test I took. Faint but still looks positive to me.
