Positive? 7DPO

Karylene

I just got off the IUD kyleena in November had a regular period in December kyleena never took my period I still had a regular cycle throughout now December 15 was the first day of my last period which would put me at 7DPO and I’m just wondering is it even posible to get a positive this early? (The second lines popped up in less than a minute which was fast)
