Low and slow rising hcg. Help!

Alissa • Dear son born 5/7/18. Three angel babies. Dear son born 8/27/20 and pregnant with our first girl and last baby Pittsburgh PA-C

My inital hcg was only 62 at about 4w and 48 hrs later it only increased to 105.

My ob had me wait 72 hours this time and my level increased from 105 to 279. Based upon my LMP I am 4w and 5d.

Has anyone had such low and slow to rise levels and ended up with a baby?

Ive had two previous miscarriages and also a normal pregnancy that resulted in a healthy baby.

Any insight is welcome! Thank you loves
