Threatened miscarriage??

Je

So I went to the er tonight because I started bleeding really bad like soaked through a pad my underwear and my pants bad. Well they did tests and an ultrasound and we saw a heartbeat which is good but the heartbeat was slower then what it should be. They said I have a threatened miscarriage. I’m so scared I have a higher chance of miscarriage and I’m only 6 weeks along. I am full of all kinds of emotions. I have to go day by day, getting blood tests and praying that everything goes well and my baby is healthy and I don’t loose it.

Has anyone else been through this? And advice or thoughts?
