I want to cry

h

I miscarried the end of October. I found out I was pregnant a few days ago. Friday I will be 5 weeks. I did an HCG blood test and my levels are at 329. The nurse said my levels are low but it’s still early. I have another blood test in a week. I can’t go through a miscarriage again. Has anyone had low levels in the beginning and carried a healthy pregnancy?
