I need help or answers

I had my period the 2nd to the 6th. Okay I looked it say you shouldn’t even test positive on a pregnancy test until 4 weeks. I am confused cause I am 100% sure of my period and then I guess I got a positive on a test. But I don’t feel 100% sure to trust the test. Cause I know there is implantation cramps but I been cramping for like 2 day. But I know that if I am I can’t do it, I can’t have another one right now with all that I am going threw. What are you guys thought.

And if you have something rude to say just don’t say it
