HCG Levels

Sydney • 6 angels 🤍🤍🤍🤍🤍🤍 Son via adoption 🩵 Due with miracle boy in Feb 🩵
I got my BFP (and I mean it was a big, bright line!!) on Monday. I went in that day for blood work and found out that my HCG was only at a 34. They had me go back yesterday to have another blood test and today they called saying it had only gone up to 41. 
I just lost a baby last month, and I am terrified that I'm going to lose this one too. 
Did anyone have a similar situation and have a healthy pregnancy?? I think I'm around 4 weeks, but I tend to ovulate late on Clomid, so I could be earlier.
