14 weeks and have a sub chorionic hemorrhage

We know what we are having a boy. This baby is wanted, was conceived in the first try we are blessed however now I am scared out of my mind that he won’t be staying. I went to the ED so much blood I soaked the seat of my car was running down my legs bled through a pad in the 40 min drive to the hospital. He had a strong HB 169 and was moving on ultrasound that was Tuesday night. Wednesday AM on hand held ultrasound he was still moving. I stopped bleeding then a day later bled a bit more and I haven’t bled since. I’m scared I have a 30% chance of losing him. Please tell me I’m not alone in this.
