No Blood tests

Helen • I am 30 yrs old. Been with my partner 5yrs. He is a guitar teacher and I am a home carer. Bought our first house last year. Now have our first child. A son named Harvey born 27/10/3016
I don't know what to do about my local doctors refusing to take a blood test from me. I am 10 days late but still getting negatives. I had what I thought was a positive on a test called early signs but I am not 100% Sure as it was not a complete line. Is there anywhere else I could go to get a blood test done or should I be strong and demand a test when I visit my doctor in Feb? The stress and worry of not knowing if I am pregnant or if my periods have stopped because something is wrong and the longer I leave things the worse it might get. I am sat here crying whilst I write this because all I want in life is to be able to carry a child of my own and the thought that I have done something or not sorted something that has been wrong with my body and caused infertility would be too much for me to handle.
