Low HCG but Doubling?

Leila
Does anyone have any positive experiences to share? I went in for a blood test at 12 or 13 dpo and my HCG was 22. I went in 42 hours later and it went up to 58. I'm super happy it doubled but freaking out that the levels are so low. I had a miscarriage in September at 11 weeks and I'm just praying I don't go through it again and this is my rainbow baby!!! 🤞🏼🙏🏼🌈👶🏻
