Was it a miscarriage?

I took 2 different tests. Both postive. 1 week late in my period. I started bleeding

I thought I was pregnant. told his parents about me having a miscarriage. They laughed. Said I didn't have one. That we were stupid to think that. They said I probably miscalculated when my period was or took something to show a false positive? .. I'm hurt that they would laugh at me.. ifeel stupid
