Left over hormones from miscarriage

Carrie💅🏼💍👼🏻

Hi there! I have some questions and hoping to get some answers from someone who has gone through what I have gone through. My husband and I had a missed miscarriage on thanks giving day last year and we ended up deciding to have a D&C; on December 1. I was wondering how long it took you guys to get the left over hormones out of your systems. My levels when I was pregnant was 29,691.0 and I have been going in and getting blood work done every week and my last one was 10.1 I’m still having positive pregnancy test. And also wondering if you can get pregnant with the hormones still in your system. Thank you ladies!
