How fast do hcg levels rise after taking the hcg drops?

How fast do hcg levels rise after taking the hcg drops?

Unable to answer: I googled hCG drops. If you're buying them on the Internet, They are not even human chronic gonadotropin. Therefore, Your hCG level would not rise. If you're getting them from a physician, you should ask the physician because he or she would know the composition of what you're taking. Sorry I cannot give you a better answer without more information like the brand of what you're using. ...Read more

Progesterone and hCG levels early pregnancy after ivf?

Progesterone and hCG levels early pregnancy after ivf?

Ok: Most ivf clinics only measure HCG levels approximately 9 days after a day 5 embryo transfer. However, some clinics feel that the combination of HCG levels and Progesterone levels have a more predictive value of a good pregnancy than HCG levels alone. Personally, we only measure hcg. Hope this helps and good luck. ...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

Hcg levels dropping slowly after miscarriage, pregnant or problem?

Hcg levels dropping slowly after miscarriage, pregnant or problem?

Not sure: Hard to say what slow means. Did you have a d;c or miscarry naturally. The level should become zero in a week or two after a spontaneous miscarriage but it depends on how high the level was when it started. ...Read more

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

Hcg levels at 9weeks 3 days was 76,000, levels checked again at 9 weeks 5 days hcg was 80,000. When does hcg levels plateau? Normal or abnormal?

Hcg levels at 9weeks 3 days was 76,000, levels checked again at 9 weeks 5 days hcg was 80,000. When does hcg levels plateau? Normal or abnormal?

Why checking HCG?: It would be helpful if you provided the units on those lab values. Not sure if they're different in Canada vs. US. If you are truly 9 weeks pregnant why are they even checking your HCG levels? Are you bleeding? Is the baby measuring small? At 9 weeks gestation the most important findings are the baby's heart rate and if the baby is continuing to grow normally. ...Read more

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

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

After 12 to 14 weeks: The HCG will typically double every two days during the first trimester (about 13 weeks). The HCG level will usually peak at about 200, 000 then begin a gradual decline during the midtrimester to a level of 50, 000 to 100, 000. ...Read more

Advanced maternal ag: Unfortunately it is a watch and wait scenario. After the age of 35 the risk of miscarriage is much higher. The pregnancy hormone does not exactly have to double but it does need to rise and we hope for the heart rate to stay 120-180. ...Read more

Fsh level 7.5, LH level 11, progesterone level 2.5, and thyroid level 1.8. Are all these normal? 16th day of cycle. Irregular periods.

Fsh level 7.5, LH level 11, progesterone level 2.5, and thyroid level 1.8. Are all these normal? 16th day of cycle. Irregular periods.

Sounds like PCOS: These levels show you have not ovulated by day 16 due to the lower progesterone. Typically throughout the month the fsh is higher than the lh. The lh goes up just before ovulation to trigger the release of the egg. This is what on ovulation predictor kit is checking for. You could be seeing the lh surge just before ovulation which could happen as late as day 20, or it could be high b/c of pcos. ...Read more

Blighted ovum or potential ectopic? My HCG levels doubled, then dropped twice before rising again. OBGYN is recommending methotrexate.

Blighted ovum or potential ectopic?  My HCG levels doubled, then dropped twice before rising again. OBGYN is recommending methotrexate.

Good idea: After multiple lab examinations, if there is still nothing seen in the uterus and a rising HCG, you most certainly have an abnormal pregnancy that should be actively managed. A dilation and curettage would help to figure out if the abnormal pregnancy was in the uterus. If it was confirmed that it was not in the uterus, then methotrexate would be a good idea along with continued lab follow up. ...Read more

My hcg levels are raising but not doubling in 24 hours they went from 7,943 to 9,633 could I be miscarrying?

Bad news, but..: You're partly right. The B-hcg should be doubling every 48 hours. Make sure your values were 2 days apart and not just 1 day! Assuming your practitioner ordered your tests 48 hours apart, this is ominous. Get an ultrasound to discover the location of the little rascal -- intrauterine, fallopian tube, or somewhere else. Assume it is non-viable, and prepare for a surgery if it causes big trouble! ...Read more

My hCG levels were at a 47 11dpo, 83 13dpo, and then a 193 dpi. Is that a normal doubling? Could I be having more than one?

Unpredictable: Trends in the pregnancy hormone levels of multiple gestations are so unpredictable because they can have one placenta or more than one placenta, or one pregnancy could be a viable and the other could not, or both could be viable and so the rate of increase wouldn't really predict anything. the only way to know is an ultrasound when your levels reach 2000. ...Read more

Ultrasound: There is wide variation on HCG levels in normal pregnancies for the levels to be reliable indicators of multiple embryos. Examination by ultrasound would be more reliable. See this site for HCG levels. http://www.babymed.com/hcg-level-in-early-pregnancy ...Read more

I got u/s at 5 weeks 5 days. Hb was 99 hbm, 3.8mm crl, and gest sac was 5 weeks 6 days. Hcg levels are doubling. Any indications of a non viability?

So far so good: I usually like to see a heartbeat at six weeks or later. The fact that you saw it so early is a good sign, even though it's slightly slow. Over 100 BPM is best after six weeks. I'm sure you have another ultrasound scheduled? Hold tight! it looks good for how early you are. ...Read more

I'm pregnant an my hcg levels was 126 2weeks ago an now 500 its not doubling an we cannot see the baby what's going on?

Probably normal: HCG levels double about each week so this rise in HCG is actually fairly normal. You cannot see an embryo on ultrasound, even by transvaginal ultrasound, until the HCG level goes above 1000. Keep monitoring and things should clear up for you in a week or two. ...Read more

I recently had an ultrasound that showed a markedly thickened and irregular stripe, 23mm.my hcg levels are more than doubling every two days,?

See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, rapidly doubling HCG levels mean pregnancy or tumor of the chorionic tissue. You need to discuss it the the doctor who is ordering the tests. ...Read more

My HCG levels are slowly rising but not doubling every 2 days. If I don't miscarry, will my baby have health issues due to chromosome problems?

No: Your HCG level should increase by at least 50% in 48 hours in a viable pregnancy. It doesn't always double in 48 hours. A rise greater than 50% but less than double doesn't mean that your baby has health issues or chromosome problems. Best wishes! ...Read more
