Brown Clots

Hi! 
I need some answers since I'm really worried. I tested positive on the 3rd and went in to see the Dr. My urine test at her office came back negative. I tested again at home and all my home tests are coming out positive. I was supposed to get my periods on the 7th. I started getting lite brown spotting from the 9th and it's on and off since then but yesterday when I wiped, I saw a huge stinky and smelly dark brown discharge. And again this morning I had the same clot but with no smell. I had dark pinkish or could say very lite red discharge right after the first brown Clot. If I go by my home tests that came positive, I would've been 5 weeks pregnant by now. Please help!!! 🙁
