What time of pregnancy do Beta HCG levels

what time of pregnancy do Beta HCG levels keep on doubling after every 48 hours?

Beta hCGFirst detectable in plasma 7 to 9 days post-LH surge, doubles every 2 days, peaks at 8 to 10 weeks of gestation(~100 IU/mL, begins to decline at 10 to 12 weeks, plateau at 16 weeks till term.

Thank you.

Till 60 to 80 days or 10 th week of pregnancy …
