I'm terrified!

Shelley • 👨🏻🤰🏻🌈👧🏻👼🏻👼🏻🐶🐶🐶🐱 Currently pregnant with my rainbow baby boy, after a loss at 10 weeks 2 days and a second loss at 17 weeks.
My husband and I spent some time outside today, just walking around enjoying the weather, nothing strenuous. All of a sudden I felt something, I was bleeding... A LOT. Within a minute it had soaked through my underwear and jeans. We headed straight home, it took us about ten minutes to get there. When I got home, I went into the bathroom to clean up and put on a pad. As soon as I sat down on the toilet, I started pouring blood..like someone had turned on a faucet and then I passed a large clot, about the size of a golf ball and then 3-4 smaller clots. That was around 4pm today. I'm still bleeding some. Now I'm at the ER getting checked out. I'm so worried.
