5 weeks preg and bleeding?? Please read

KaY • going to be a mummy to my boy Levi😘
So its Sunday today and I've been bleeding since Monday night. Been to the hospital twice due to heavy bleeding, had blood test and was monitored over night. TMI, I passed big clots so its really worrying me, the doc said its a threatened miscarriage :-( I broke my heart as I've been trying for a baby for 3 years. I've had scans but it's too early to detect a heartbeat so I have another scan a week on Tuesday which is the 6th September. I was rushed to hospital Thursday due to passing big clots and losing lots of blood, the scans show the sac is still there even after the heavy bleed and clots. Am I likely to misscarry or is there still hope for me?? I'm so scared this is my first pregnancy too..
