I Took A Home Pregnancy Test In The Morning With

I took a home pregnancy test in the morning with the first urine and got an extremely clear positive, it is still visible now about 2 hours on. I took a second home pregnancy test a half hour after the first one and got an extremely faint positive line. It is now about 2 hours since I last tested and it has come to a clear negative. Am I pregnant or not and is there a chance for a false positive?
