Miscarriage at 4 weeks. Is this normal?

Laci • Mommy of 3 girls and Expecting our first boy! 👶🏼🤰🏻

I had my first miscarriage January 17th at least that when the bleeding started. I bled for 3 days like a light period with no clots or discharge. Is this normal? I had blood work done the 17th it was 100 and by the 21st is was at 12. So you think the baby and sac were absorbed? Should I take another test to see is it shows any htc? So confused and heartbroken! 😔😭
