My Hcg doubling time went from 42 hours to 68 hours. Does this mean I'm most likely going to miscarry. ?

My Hcg doubling time went from 42 hours to 68 hours. Does this mean I'm most likely going to miscarry. ?

It really depends: The significance of doubling time depends on how far along you are in pregnancy. The rate of increase in HCG peaks at about 8-10 weeks then starts declining after that. If you're less than 8-10 weeks along, then a combination of symptoms, clinical judgment and serial ultrasounds are at least as important as HCG levels in determining the fate of your pregnancy. Please talk to your OB. ...Read more

Dpo/hcg levels: 14=233; 15=389; 16=683; 19=2821; 21=4643; 22=6533; 24=9596 (86 hrs doub. Time). Can high early hCG = earlier decline in doubling time?

Not really!: The 'doubling time' is not strict, it's a rough guide. Normal pregnancies may only go up by 2/3 in 2 days not 'twice.' furthermore each level is accurate to about +/- 15%, they are not 100%. Your numbers look normal, i wouldn't wear out your calculator doing this kind of thing. ...Read more

My beta hcg was 59.6 progesterone 20.5 on 4/15. I was started on prog suppos. Today hcg 234.8, progesterone 27. Is 72.4 hrs doubling time ok?

Probably adequate: BHCG should increase by 66% every 48 hours. There can be variation though so this should not be used as a definitive tool to confirm pregnancy viability. ...Read more

I 'm approx 6 weeks. Hcg 1812 2days ago & 2724 today (52 hrs later). Doubling time about 68 hrs. Mean anything? No ultrasound for 10days. Thank you!

I 'm approx 6 weeks. Hcg 1812  2days ago & 2724 today (52 hrs later).  Doubling time about 68 hrs. Mean anything? No ultrasound for 10days. Thank you!

Difficult to say: It usually requires 3 values to fully determine a pattern. Since 10 days a hve passed a repeat ultrasound may be helful. Please discuss this with your ob. The values need to rise at least 60% in 48 hours. It does not need to precisely double in that time. ...Read more

My hcg was 31 at 13dpiui and 50 at 15dpiui. My doctor didn't seem optimistic. It's about a 70hr doubling time. Can it still be ok?

My hcg was 31 at 13dpiui and 50 at 15dpiui. My doctor didn't seem optimistic. It's about a 70hr doubling time. Can it still be ok?

Yes: Over 48 hours, it should go up by 50% and not necessarily double. Keep following it. As long as its rising by 50% every 48 hours, you can still have a normal pregnancy. ...Read more

My HCG levels at 17DPO were 261, at 21DPO they were 669. This is a doubling time of 70 hours. What are my chances of a healthy pregnancy?

My HCG levels at 17DPO were 261, at 21DPO they were 669. This is a doubling time of 70 hours. What are my chances of a healthy pregnancy?

Hopefully good: There is a wide variation in the HCG levels in normal pregnancies and you should not pay too much attention to the levels, in isolation. I wish you good health and a healthy baby! ...Read more

Hcg beta at 14dpo=70 16dpo=106. Doubling time= 80 hours. What are chances of miscarriage? Slow x2 time happened to me in last (healthy) pregnancy too.

Hcg beta at 14dpo=70 16dpo=106. Doubling time= 80 hours. What are chances of miscarriage? Slow x2 time happened to me in last (healthy) pregnancy too.

May be normal: You cannot predict anything from these data. Do not take the "doubling time" too literally, there is some variability and 166% increase in 48 hours is still within normal many times. Good wishes. ...Read more

14dpo hCG 174, 16dpo hCG 342, 22dpo hCG 5656, progesterone 54. Could fast doubling time indicate molar pregnancy?

14dpo hCG 174, 16dpo hCG 342, 22dpo hCG 5656, progesterone 54. Could fast doubling time indicate molar pregnancy?

No: Molar pregnancies are almost never diagnosed this early. Good news! The hCG is rising at a mostly appropriate rate, the "doubling time" is not exact. Why are so many quants being done so many days in a row? ...Read more

At what level do hCG numbers start doubling at a slower rate?

Post FET Hcg not doubling. 195- (72 hrs) 597-1056-1807 tests 48 hours apart. Thoughts? I'm so worried.

Post FET Hcg not doubling. 195- (72 hrs) 597-1056-1807 tests 48 hours apart. Thoughts? I'm so worried.

Doubling: every 48 hours is a rule of thumb. Yours are close to doubling. I wouldn't stress out now. Wait till the planned ultrasound...... ...Read more
