What is going on?

My LMP was 26/11. BFP on 26/12. Had a private scan on the 6th Feb. She said there was no hb and she rang PAU and they said come in the following Monday 12th Feb for conformation scan. I called and cancelled due to brown smudge and the beginning of the end. Anyway it didn't develop into anything. I did another test today. Digi saying 3+ and very bright lines on cheapie. No bleeding, nothing. I'm starting to get my hopes up but I just know if I call for a scan the bleeding will begin and I will look like a crazy lady. I think I'm just asking for hope or some sense being shaken into me.
