Early pregnancy HCG levels

Kayla • Wife & mama raising two babes with my angel baby Ada in heaven. ✨ 10/3/2020 Rest In Peace my beautiful baby girl. 💖

I know it doesn’t necessarily matter about the level just that it doubles every 48 hours. I had my levels drawn yesterday and it was 26. I know I’m very early. Like 3-4 weeks. But I have hardly any symptoms besides somewhat tender breasts. My hpt are still showing positives but not very dark (pic for reference.) this would be my 4th pregnancy so maybe my body is used to the horomones and that’s why it was picked up so quick? I’m trying not to panic or drive myself insane but it’s hard not to. I lost my baby at 9 days old and this would be our rainbow. Has anyone else experienced low HCG levels and have a healthy pregnancy?
