Hpt positive really early!

So I'm pretty regular with my periods and I assume probably regular with ovulation. The past week iv been experiencing cramps and extremely sore boobs. Today I'm 9 days away from my period and something told me to take a hpt. I did so in the late afternoon I barely needed to pre just a few drops and it instantly showed a positive line. Then right now I took a digital test which I barely peed like just a few drops and it came back positive! Isn't it crazy!!!!!
