was I pregnant?

so I just kinda had that feeling if that makes sense that I was pregnant and I was sick and nauseous and I was never really hungry or anything and I was scared to take a test. well I decided I was going to take one on a Friday but started my “ period “ on Tuesday it wasn’t like a normal period. it was extremely light and not like my normal periods. it was very weird. I was still feeling nauseous and not hungry etc so to ease my mind I took the test and it said positive so I called my local health clinic and they took a pee test and it was negative. so my question is WAS I pregnant? did I have a miscarriage? this has happened about 2 months ago but it’s been lying in the back of the head since it happened.
