I read it can be between 90-150. I went for an ultrasound at 6 weeks 6 days and he said the heart rate was normal. He didnt give me an exact number other than normal. Another doctor said as long as they see a heart beat your fine
I've had many miscarriages I only have one baby currently I'm 9 weeks I got my first us at 6 weeks saw the baby and heartbeat it was that low to he says that young it's normal so it's okay it'll get higher. Good luck
Goood luck today!!
How far along are you?
I also had a miscarriage last July 2016 and just found out I'm pregnant. I'm also very nervous. Having seen dr yet but getting blood drawn as we speak.
