Subchorionic hemmoraghe

Hope
I've been having brown old blood on the toilet paper after I've been wiping. It later progressed to bright red but in very small amounts. I woke up early this am because I could feel something running down my legs. Went to the bathroom and it was dark red blood. A good amount too. I got scared and had trouble sleeping. Went to work and called the doctor. They got me an emergency appt. The bleeding kept getting heavier. I had to go home and change Bc it got all over my pants.  They told me I have a subchorionic hemmoraghe that is causing the bleeding. They said it could absolve on its on, or maybe not.  But it does have a high risk for MC.  It's a waiting game now. But it's very close to the sac. They gave me some progesterone and ran some blood tests. Hopefully everything is fine. I'm about 7 weeks. Please pray for me. The baby looked fine in the ultrasound and they detected a good heartbeat. Has anybody had a subchorionic hemmoraghe ?? Just want to know your experiences. I have been TTC for 18 months and I really want this baby.
