Im confused, 2 bfp on hpt but 1 bfn on dr. pregnancy test?

Ok I get pregnancy symptoms early, like with in a week of conception early. So for weeks I have had symptoms and a week before my af was to arrive I begin takeing pregnancy test. I go threw five digitals. All bfn. two days before my period is to arrive I take the dollar general early response test and get two bfp one is faint the other is darker (one was fmu). So obviously I go to the dr. The next day (Now this was at 6:30pm so not fmu) and get a negative. I'm takeing a blood test tomorrow of course but I'm confused am I pregnant? Did I have a chemical pregnancy? If so wouldn't I be bleeding (I am not bleeding just clear discharge) I know I seem worried but this would be my first pregnancy since my miscarriage and I know I'm not crazy.
