New pregnancy ?

Chairty

well... the thing is, is I had a blighted ovum mid July... after bleeding stopped had a 4 day very light cycle... and have been testing down to see when levels are at zero, but it has been taking forever... last hCG was done last Thursday it was 15... i took a test the Monday before that Thursday (last Monday) that’s the top pic... So I am trying to figure out if this could be a new pregnancy
