Dr killed my hopes

I went to urgent care today because I was feeling sick with the flu I had no energy and sore throat. I also told him that I was trying to get pregnant and that last week I was having lower back pains for 3 days straight and that my (.)(.) were pretty sore even when I laying in bed and I turn over and he said I don’t think that your pregnant a lot of times it could be because of you period or your body produces a lot of hormones, I told him that I have taken a few pregnancy test and that they were all negative and that if it was possible to do a blood test and he said no urine test is more accurate than a blood test he offered to do a urine test and I told him no I know it will be negative so I came home with my heart broken and lost my hopes of being pregnant this month, although my boobs are still very sensitive and mild lower back pain and I feel like AF is coming 😞😞😞 I am 13 DPO and 4 negative test😢😢 is anyone else going through the same as me
