HEAVY FAUCET LIKE BLEEDING

Em
So about 30 minutes ago I was laying in bed getting ready to go to sleep when all of the sudden I feel a warm sensation in my Varuna I immediately get up and walk to the bathroom where my husband is showering too scared to look down and open the shower door where he turns around and looks at me confused, then looks down and his eyes got the widest I've ever seen them get so I look down and its blood running down both my legs and still going. I get in the shower with him yelling what the hell is this and him trying to calm me down... I sit on the the seat and it feels like I'm peeing myself...Except it's blood And I cannot hold myself for a few seconds to get up and get on the toilet. My husband helped me get dressed, and Was checked into the ER, and had some blood samples taken. This is 2 months after I miscarried on July 23rd this year(my hcg went down to zero) , and after I was feeling hopeful because I've Been feeling morning nausea, fatigue all the time, no appetite... If it's another miscarriage idk what I'd do. This would be my third miscarriage, and I can't handle another one. I'm crying my eyes out.. 
I was supposed to test in the morning!!
