Quiestion about Beta HCG draws

Halie • Brian P Raines 🥰10/05/2018 💍02/05/2019 Delilah R Raines💞12/10/2020 @ 9:18am weighing 8lbs and was 20.5 inches long. Baby Raines #2 due October 24th, 2022 💞🥺🥰🤰

These are my results from yesterday.

Now from what their ranges are it’s saying I’m only 1-2 weeks post LMP and I’m actually 3-4 weeks LMP.

Is this a sign of a miscarriage or is my levels just rising slowly? I haven’t missed my period yet either. 🥺

Sorry if this isn’t supposed to be asked in this group I’m just not sure which group to post it in. 🥺💞
