hcg levels low?? 😩

My last period was Feb. 16th I had brown discharge pink and also faint red for about a week. I went to the ER last night and they said I've probably miscarried because My levels were 104. The discharge/bleeding has stopped since then I have a follow up to check my levels again. Is a level of 104 normal? so early in pregnancy. Im heart broken at this point.
