Period cramps. No period yet. Pregnant?

I got cramps two days before my period was supposed to come just like every other month but it hasn’t come yet and I’m wondering has this happened to anyone and you ended up pregnant? Im still cramping like a period is about to show up. I’m not late yet but took a test, Because why not, and used first morning pee and there was a faint line. Anyone else been though cramping when a period was supposed to come. Haaaalllp!!
