How long does it take

How long does it take for HCG hormones to leave your body after birth? I took a test at 3 months PP and 2 digitals say pregnant. Just trying to make sure it’s accurate before I feel any type of way about it. Possible reasons it’s still positive from birth or actually pregnant? Calling OB tomorrow but in the meantime just asking for thoughts. I had my first PP period last month starting May 15th
