HCG need to be 0?

Joy

Hi! So this may be a totally dumb question, but does HCG have to be 0 to get your period again after a miscarriage? I’m asking because I had bleeding, then spotting gradually decreased but now I’m bleeding again!! 😩 I’m hoping it’s my period so I can start trying again but I still got a vfl on a pregnancy test. This is the worst 😥
