Positive 2 week after mc

I started bleeding 29th June and it’s now the 12th July… still this positive after missvarrisge the last scan I went the day after the pain and bleeding started there was no sac anymore. Could I be pregnant still or is this normal to still have a positive this strong? I know I shouldn’t be but can’t help but wonder… can I get try to get pregnant again with hcg in my system still (I haven’t had sex since before my mc)
