So confused

I was supposed to start my period on the 24th it is now the 31st and still no signs. I've taken a few at home tests and some were positive and some were negative so I figured I should go to the er to get blood work done ( suffered a miscarriage about two months ago so I started panicking) the er Dr was very rude I gave a urine sample they tested it and it came back negative and he was just gonna send me on my way, well I wanted a blood test done so I asked for one as he laughed at me told me all I was doing was wasting both of our time and that it was gonna take an hour to an hour and a half to get the results back. I said I didn't care I wanted to know. He was back in my room within 20 mins and told me the results were negative and asked if I was finished wasting his time. Like WTF?! No!! He had no proof that it was negative and my discharge papers didn't say negative ( when I was pregnant right before I miscarried I went to the er with stomach pains and my discharge papers said pregnant). I am so confused and I have no idea what to do from here can someone/ anyone please help?!?!
