First chemical

So I have experiences my first chemical.

I got my first positive last Sunday and had been crampy for the past week. My tests started getting lighter and finally rushed to the ER today after bleeding. The doctor was so rude he said he didn’t even think I was pregnant. I showed him all the 9 positive tests I took and he said “at home tests are not accurate.”

Moving forward, I’m scared of even trying again thinking the same thing will happen. I am in pain and more emotional pain than anything else. Does it get better ?
