Constantly doing pregnancy test

I miscarried in December and found out I was pregnant at 9 days ago. 
I took a first response which was positive then a clear blue digital which said pregnant 1-2. I have since taken about 4 clear blue distal test and they still say 1-2. I'm desperate to see the hormone level increase. 
I have taken cheaper tests too and they have become darker. Am I just being paranoid? 
From the uk so not had DR check HCG levels.
