Positve HPT a week after period!

[Zeppy]

HI everyone,
Ok, I know there's alot of confused woman on here, and I am just another one. Here is my weird story.
I went 13 weeks without a period, I was hopeing to be pregnant, but wasn't. All pee tests and blood tests were negative, so about 4-5 weeks late I had an ultrasound which showed Polycystic Ovaries. A about 2 weeks later I had blood work done which showed everything, even all my hormones normal. That was confusing. I finaly got what I thought was a period last week (wednesday 19th August) which seemed like a normal one. A day before the bleeding started I had done a HPT and I thought maybe there was a extremely faint positive line, but I also though it was one of those shadow lines. So wednesday this week (26th Aug) I thought why not do a test (I am a bit of a test-o-holic) and to a big surprise it's positve, faint but a deffenent positive. So I tested yesterday and yep, still a line, about the same colour and again today, I think maybe a little darker. So I know I either was or am pregnant.
If I had a really early M/C would the test show up positve like it is or should it be negative by now? Or could I have had "hormone bleeding"? I think it was to heavy for implantation bleeding.
I am seeing my Dr on Tuesday but thought you lovely ladies may have some ideas.

P.S. We have been trying for about 18 months so you can imagine how frustrating it all is.
