Help me please

o I had a miscarriage on July 9th and I think I ovulated around the last week of July, I had unprotected sex twice but he came like three mins after he was not inside me. I took a test and it looks positive ( this pic after two hours)but I know blue ones are always faulty. So I took another one and it’s really negative. I don’t want to be pregnant at all so I’m just really having bad anxiety. Am I over panicking or is there a possibility I am pregnant I ALSO HAVE CRAMPS but I did have them as well and ended pregnant last month
