Bleeding, positive blood test

Help! I'm currently 15 dpo..my period looks like it started yesterday (day of expected period of all days) but what's weird is I've tested postive all week! I go to the ER for the bleeding and suspect a misscariage/chemical/negative pregnancy test. Well, I got a positive blood test! But my Quant or whatever was only 14. Any similar stories have a good ending?

Three of my test from last night and this evening before going to the ER this evening.
