Scared

Hi everyone, I'm currently pregnant w my rainbow baby and had a strong positive FRER on Wednesday when I went in for my first HCG draw. I have my second draw today, but when I tested again with FRER my test line was barely visible 😢 has anyone had this situation turn out ok or am I about to lose my second baby in three months? I'll get the HCG results back over the weekend at some point. Looking for comfort and very sad
