am I having a miscarriage

Shelby
I took this test about 4 days ago! Looks like I might be prego. 
Well today I was inside ordering food and it felt like I peeped my pants. When I went to bathroom It was blood! It was enough to fill a pad up. I went home and I'm not bleeding as bad! I took Two prego test after bleeding an this is the results 
I've had a missed period for 4 weeks now. What should I do? 😭
