2 weeks pregnant? Positive test..

My period started December 15th. Yesterday I got a positive pregnancy test. I do not understand at all how I can be testing positive for pregnancy so early. I took a pregnancy test the day of the 15th right before I got my period and it was VERY negative. And then yesterday I got a positive pregnancy test after a normal 5 day period. Someone help me figure out what’s going on rn.

So I’m 2 weeks 1 day pregnant now. But that does not make sense. At all. But I’m also spotting and cramping.

I really doing know what group to put this in so I’m blurring the picture of the tests that show positive!!!

But someone please help me I’m so confused what’s happening to my body.
