Positive pregnancy test because of miscarriage?

Mindy

I had a miscarriage Nov 9 or earlier. My husband and I had unprotected sex twice since then and I just took a pregnancy test and within seconds it came up positive super dark lines. I’m not getting excited because my hcg levels are at 62,000 as of Wednesday. Is this why it’s positive? When I got pregnant my first time, I peed constantly at night and that’s what’s happening again. So that’s why I decided to test again because I have a feeling that I’m pregnant. Any comments would help! Thank you.
