Heavy bleeding but hcg doubling?

Tori • Mumma to a little boy 💙👼🏻👼🏻 No.2 due July ‘23 🤍

Has anyone experienced unexplained bleeding and your hcg double? I’m 5 weeks and for the last week have been bleeding. First 2 days was spotting then it went to a light bleed and now it’s heavier. I find I bleed more when I’m walking around or lifting up my son?
