Hello everyone, I am trying not to worried but is impossible not think about!

Please if anyone is in the same boat give me some advice! I had 3 children all healthy pregnancy! After that I had 3 miscarriage... and now I am pregnant again and very concerned; my first Hcg was on October 28 at 4 weeks and 6 days, the Hcg number was 1583. I did again other Hcg on Wednesday November 4th the results comeback Hcg 2433 and progesterone 11.79. I am very concerned about this numbers. ;(
