still testing positive after MC?

cat • mama to 3 earthside, 2 angel babies. Pregnant with rainbow twins due April ‘25. 💜

Had MC at 5 weeks on 7/26, beta went from 700 to 500 on 8/9. That was the last blood test I did. I don’t

know if and when my levels zerod out so now I’m confused if this is old hormones or new pregnancy. Haven’t had a period yet
