Need encouragement on these HCG levels


I’m 5wks got my 3rd hcg done which was 362. I got 2 others hcg at 3wks6 it was 17 and 4wks1 it was 30. My REI had me wait a week to repeat my second and third. I know i should be happy that my numbers increased. I just thought it would be higher. Especially after i see some the others ladies levels and their way higher. I still can’t help but worry. This is my 4th pregnancy in the last 6 months.
