How’s this possible

Excuse my crusty hands, so I got a positive test.

But the thing is my period isn’t for like another week and half, glow has me at around 2 weeks and 6 days. How exactly is this possible? This has never happened to me with any of my other pregnancies. I’m sure my last period was a period, I had clots, lasted the normal amount of time, was exactly like a period. I’m in shock 😨
