Negative beta and positive HPT's

I'm around 11dpo maybe give or take a day and yesterday I got my first faint, faint BFP on an internet cheapie. I had an appointment with my OBGYN and he examined me and said everything's fine, having normal discharge, no sign of infection, and ordered me a quantitative HCG blood test. He called me later yesterday and left me a message saying it was negative. I took another internet chaepie (a different brand) and once again, another faint faint positive. I'm so confused because I took another one with FMU today and there it was, another faint positive. I'm reading these within 3-5 minutes so I don't think it could be an evap. I finally got frustrated and called and asked for what the number was and they said 0.5. I'm also having a lot of white lotiony discharge, a lot. It doesn't itch or burn or anything but I'm so confused   . Thanks in advance for any input.

edit: here's a picture of the different brands. They were scanned right away but my scanner scans with a low brightness and a high contrast for some reason so that's why they look older:

They dont appear to have any color but im on my phone so i may not be seeing well. Chemical pregnancy maybe? Thats wierd

You're not on any hormonal medicines that could effect it right?
You don't just get multiple tests for no reason...but I'm not sure how you could even have a positive with levels that low. I would keep testing to see if the line gets darker/lighter. If it does ask for another blood test.
Um you dont drink lots of apple juice do you? I know i sound crazy but i read a bunch of poasa tried it out and it can cause a light line.

You may have had a chemical pregnancy. HCG is secreted in the blood first and then the urine, so it's possible to have a negative beta yet faint HPTs as the HCG leaves your system. I'm sorry.
