Has anyone had a chemical pregnancy before? Has anyone ever had their numbers stop doubling and then start again? If not, how soon after were you able to conceive? At 4 weeks my hcg was 28. After 4 days it went to 150 and the next day it was at 248. 2 days later my blood work came back at 249. My dr said it could be a chemical pregnancy but we need to do one more hcg test to confirm. Im a little concerned about my estrogen and progesterone. My estrogen and progesterone were low from the start so they put me on supplements for both. Does anyone know if levels vary from pregnancy to pregnancy or if i could just be deficient?
