Ok well the day of my last period was 13th July 2009 I'm 17 and I'm not to sure if its pregnancy I've taken some tests but I had a misscarridge last year and had a lot of problems with HPT getting a positive result so far I have had all the signs and only a fant positive test then I went to my doctors and took a test which came back negative I have no idea what to do because my doctor won't let me have a blood test or a scan. Last night I had a light watery bleed that lasted less the a hour and there was barely any blood I have no clue what's going on could someone please help me? If I'm not pregnant then what on earth is going on?
