HCG low

At 14dpo (4 weeks) my HCG was 46. At 16dpo it was 83. That’s barely under not doubling. Has anyone been close to this and it been okay? My next blood draw will be at 19dpo on Monday. If this isn’t okay, it will be my 4th miscarriage this year and idk if I can handle that. Please pray that everything is okay! Thank you so much!
