HCG more than doubling then slowing now rising well again ??

May 11 308
May 14 1116
May 16 2011
May 18 3225 (ultrasound showed sac measuring right on dates no fetal pole or yolk sac yet rescan June 4)

May 22 5306
May 24 6689
May 28 11285 6wks 4Days

Morning sickness like crazy. No bleeding or spotting history of non doubling HCG but have never tracked this much feb blighted ovum. Sept ectopic The report says favourable and suggests rescan for crown rump length. Is this HCG stuff common ? If I put it in a calculator from first to last is says normal increase but if I break it down it says lower than normal ?? Just stressing and can’t find info


It is useless to do hCG levels at this point, a sonogram is more reliable


  • As your pregnancy progresses, the hCG level increase slows down significantly.
  • Between 1,200 and 6,000 mIU/ml serum, the hCG level usually takes 72-96 hours to double.
  • Above 6,000 mIU/ml, the hCG level often takes over four or more days to double.
  • In general, when the HCG level reaches 7200 mIU/ml, a yolk sac should be seen.
  • At an HCG level greater than 10,800 mIU/ml, there should be a visible embryo with a heartbeat.
