LMP and AOG

Hello mga mi, ask ko lang po kung bad sign po ba if malaki ang difference ng LMP at AOG? Based on LMP ay 8 weeks and 5 days pregnant. Based on AOG ay 5 weeks and 1 day. Just curious lang po. Nagka miscarriage po kasi ako dati and napansin ko po malaki po yung week difference ng AOG at LMP.
