Tw mc

I had some positives the line for 5 day's they were getting darker. I was 3 days late for AF. Then I starting to bleed it was a light bleed then a medium then light and nothing. It only lasted 3 days. I went to the doctors they did a urine test it was negative. Then they did a blood test it was negative but didn't check my hcg levels for the value just a regular hcg test. Today I took a test I started to see a vfl after having all negatives all that week since I started bleeding. I added what my negative looked like when I started bleeding. It's the one on the tp. It was all taken within 3 minutes. I will attach my positives. I attached the ones from today. Has this happened to anyone else? The doctors said it was miscarriage.
