Just curious

So I had to an etopic back in the beginning of April they gave me the shot now I went until my last hcg was 456 I just couldn’t go no more I was depressed and sad just unmotivated to keep seeing I didn’t have my pregnancy anymore so yesterday I want for a routine check up got blood drawn and said hcg is 5 is a 5 negative or positive and is there still a chance of some left over hcg in my body because I just had a normal period after I bled for about almost 2 weeks after my etopic
