HCG Levels in Pregnancy

Whether it is their first pregnancy, or they have been pregnant before, many women have heard the term “hCG” while they are either trying to conceive, or shortly after they conceive, but they don’t necessarily know what it means.

In the medical world, hCG is short for Human chorionic gonadotropin which is a hormone that a woman makes when she is pregnant. It can be detected in a urine sample or a blood sample as early as 10 days before your period should start. However, it can take until several days after you miss your period for these levels to be high enough that they can be detected.

The hCG hormone helps sustain a woman’s pregnancy until the second trimester when the placenta starts functioning fully and takes over. It also helps create the testes, secretes estrogen, and helps develop the placenta.

For women who have faced infertility issues, or who have had problems with miscarriages, doctors will routinely draw blood to check the hCG levels 2-3 times a week in early pregnancy. This is because hCG is supposed to at least double in a 48 hour period until it reaches a certain level, when it starts to decline. If the levels are doubling, it is often a sign that the pregnancy is viable and progressing as normal. If there is only a small rise in the number, no rise in the number, or a drop, it can be the first sign to a doctor or midwife that this pregnancy may not last through the first trimester.

There is no “norm” in the range for hCG levels in a pregnancy. They generally fall into this range.

Week since last menstrual period began Amount of hCG in mIU/ml
3 5 – 50 (less than 5 means you are not pregnant)
5 19 – 7,340
7-8 7,650 – 229,000

If hCG levels are taken and they not only double, but triple, quadruple or more, this is often a sign that there is more than one baby in the uterus. When a woman is pregnant with multiples, her hormones will rise much faster than they do when it is just a single pregnancy.

If you have questions about your hCG levels, be sure to ask your doctor or midwife. They are the only ones who can correctly test, judge, and give you answers regarding the health of your pregnancy.

    also based on my research and based on the first day of my last period my hcg levels are high even though they are moving very low bc as of today i should be 4 weeks and 5 days with levels of 4700ish if i am having more than one baby is it possible to still move slowly and not see anything in the ultrasound or is it possible that i was having more than one baby and one or more miscarried and one is still alive? just a thought

    so im just going to put my whole situation from begainning to end on here to help eveyone understand exactally what is going on with my pregnancy to better help you help me if possible…

    the first day of my last period was march 23rd it lasted till the 29th. i started spotting and then slightly bleeding on the 7th of april so on the 9th when it did not stop i went to the hospital after taking 2 home pregnancy test and getting a positive the doctor did a blood test and urine test they both said positive so they did an ultrasound but saw nothing. my hcg on the 7th was 2000. on the 9th my levels were tested again and went up 700 the doctor became concerned because they didnt double and he didnt see anything in my previous ultrasound. my bleeding stopped completely no spotting on the 13th. my next ultrasound was schedualed for the 17th, i went and when i told the ultrasound tec the first day of my last period she said im too early to see anything so she didnt bother doing the ultrasound plus my bladder wasnt full enough even though it felt like it was overly full lol and we reschedualed for the 22rd. i went to that ultrasound and they still did not see my baby. they had me come back in for blood work on the 24th finally(they should have been checking it a couple times a week) and my levels were 4700ish. i am having no bad cramping my boobs are still swelling and hurt like hell no dizziness or sickness nothing feels outta place other than my brain lol i know when you levels are moving slowly it can mean miscarraige, eptopic(which they didnt see in the ultrasound) or birth defects such as turners and down syndrome, or molar pregnancy or chemical pregnancy and probably many others. i have been researching and staying as calm as possible. i am doing my own research because i dont feel the doctors are doing all they should to monitor my pregnancy with what is going on. so i guess i am just looking for anyones insight on my situation and here others similar situations to get an idea of what might be happing to my unborn bundle of joy and hoping for the best.

    This was only a month ago.
    Me and my partner have had unprotected sex numerous times
    And I took a clearblue digital test and it’s showed up pregnant 1-2

    I had an abortion 2 month ago. No period since and 5 tests show positive. Went to doctor, he told me I am pregnant. Had blood drops and felt tingling. I scheduled urgent ultrasound and shows nothing and HCG at48. Am I pregnant? Or I still have hormones from previous pregnancy?

    I had a ectopic pregnancy in march . I found out on sept 13 I was pregnant again. My last period was aug 18. I went for blood work and more blood work. The doctor told me the levels where fine. I changed doctors before they did a ultrasound. When I finally had a ultrasound I was 9 weeks. The tech looked and looked, she found a sac no baby. They sent me for more blood work that was on a Friday. I had to go for more blood work that next Monday.. They called and told me my numbers on Friday was up from the last time I had bw done, but dropped on mondays bw. They told me I would miscarry and asked what I wanted to do. Me and my husband wanted to wait to see what happens. I am now 11 weeks pregnant, no signs of miscarriage so far. I have to go back on the 9th to do more blood work. It’s killing me to have to wait. We want our baby to be healthy but no one is really giving us any hope. We are trying to say positive and I have looked all over the Internet for a story like mine, but I’m having no luck. For all the ladies that are looking for a story like theirs I hope this helps, and when we get more info or something changes I will post again.

    I almost miscarried 2 days ago and they did the ultrasound@ the hosp, and everything is right where it should be, But they can’t find a heartbeat and it could be because it is too early.and the dr.@the hosp. said I would probally miscarry all of they way within the next few days, but I haven’t and yest. I went to my new dr. she is an actual obygn and she did some testing of her own on me and she is keeping watch on my HCG levels to make sure they are going up like they should while I am pregnant to endicate that the pregnancy will proceed like it is sopposed to without memiscarrying and 2days ago my level was@ 1500 and now it is @ 2800 and I haven’t miscarried and she said that she thinks everything is going to be alright because normally when you miscarry or that you are going to end up fully miscarrying that your number will drop instead of increasing. and now she is going to just keep watching my number each week and see where it goes from there and hooefully it stays increasing. I am only 5 wks. pregnant which means it is very early to be able to tell what might happen for sure. But, she assures me that everything is going to be fine and that the pregnancy is proceeding like it should. I guess I am just worried because they can’t find a heartbeat yet, and she said it usaully doesn’t start untill anywhere rom 4-6 wks. I’m just worried is everything going to be alright? and I hope when I go in a few days and they do another vaginal ultrasound that they can find a heartbeat this time. I am thinking it is because it is just so early and that is what she said and for me not to worry or stess myself about this. But, I am just so worried if the baby is alright or what? I’m kindof a bit confussed about it to be completley honest. Please pray for my pregnancy. :)

    Quantative hcg levels are drawn to establish how the pregnancy is progressing. Since the levels can vary so much from individual to individual there is no real way to determine who will or will not carry to term. Typically levels are drawn over the course of six days first to get a baseline level with the following two providing assistance with determination of due date and or the presence of multiples. A rise in levels with a decrease may indicate a potential miscarriage but is not difinitive. A rise in levels then a decrease and then another rise may be indicative of multiples with the loss of one. Each pregnant mother has the right to request an ultrasound to determine viablity of pregnancy. It should be kept in mind that if it is early in the pregnancy only a gestational sac may be seen until at least five weeks gestation. Remember your OB works for you so do not be afraid to ask questions.

    I am 7 weeks pregnant according to my last menstral cycle, I had an ultrasound last week and the doctor could not see a heartbeat. I also had my blood drawn and my hcg levels were 24,000, then I had another ultrasound 5 days later and still no heartbeat, the doctor said I was measuring 5.5- 6 weeks, I also had my blood drawn again the my hcg levels were over 56,000……the doctor thinks that I am going to have a miscarriage because she said that you should be able to see a heartbeat after 10,000 hcg levels. She also said that I have an abnormal gestational sac. Can anyone please help with a similiar story or any advice. Thank you!
