A balanced and healthy estrogen level will drastically improve not just the health of your child but also their chances of having children of their own.

What Does It Do

HCG is thought of as the OG pregnancy hormone, and its boosted by the fledgling placenta after conception. Men and women both have small amounts of HCG in their body at all times, but the presence of higher than normal levels of this hormone in an expectant womans urine is what sparks that positive result in early pregnancy tests. By around the two week mark of pregnancy, the HCG levels will be high enough to give an accurate result, but it can be detected in the bloodstream around seven days from conception.

HCG levels are usually higher in multiple pregnancies twins or triplets, for example providing the first indication there is more than one baby on board. This hormone also doubles each day for the first ten weeks or so of pregnancy, and moderates appropriate levels of other pregnancy hormones like oestrogen and progesterone until the placenta is developed enough to self-moderate.

Treatment depends on the mass of cells and whether it is cancerous or benign. To remove the mass, the doctor may recommend dilation and curettage, which involves sucking away the mass with a surgical vacuum and gently scraping away any remaining abnormal cells.Or, a doctor may recommend a hysterectomy, to remove the uterus.

After the removal, a person may need chemotherapy or other treatment. This may be more likely if hCG levels remain high.


High hCG levels may also indicate preeclampsia, a pregnancy-linked condition that involves swelling and a sudden rise in blood pressure. In a 2012 study, for example, researchers found that hCG levels were significantly increased in women with severe preeclampsia.

It may be safe for a woman with mild preeclampsia to wait and deliver as usual. But if a woman develops the condition and the pregnancy is at

What Role Does Estrogen Play In Pregnancy

Along with progesterone, estrogen is one of the two main hormones that get the pregnancy party started. Produced by the ovaries and later by the placenta, estrogen helps the uterus grow, maintains uterine lining, regulates other key hormones and triggers the development of babys organs. And when its time to breastfeed, estrogen promotes the growth of breast tissue and helps milk flow.

Got a stuffy nose or blotchy skin? Estrogen is also behind swollen mucous membranes and it causes extra blood flow to your skin, which can result in a red, itchy complexion. And estrogen joins other hormones to cause hyperpigmentation like darker nipples and melasma, brown patches on nose, cheeks and forehead.

What Does Estrogen Do During Pregnancy

During pregnancy, estrogen has many key effects. It helps develop the placenta and the network needed to bring nutrients and waste to and from the growing baby. For the fetus itself, maternal estrogen triggers the development of organs like the lungs, liver, and endocrine glands.

In the mother’s body, increased estrogen levels help expand the uterus, maintain the uterine lining, and increase blood flow and vascularization in the uterus and placenta.

Elevated estrogen also suppresses follicular stimulating hormone and luteinizing hormone , preventing ovulation during the pregnancy.

Further into pregnancy, estrogen also promotes the production of milk and the growth of breast tissue, and prepares the body for birth and breastfeeding.

These elevated estrogen levels can have other effects as well. Hyperpigmented skin , and a stuffy nose during pregnancy are both estrogen-linked complaints. Because it triggers increased blood volume, estrogen can also add to spider veins, swelling, nausea, tender breasts, and more frequent trips to the bathroom .

In general, these miscarriages due to low progesterone levels occur before the 10th week of pregnancy, when placenta has not yet developed.

If more than one miscarriage in a row occurs, you should seek medical help, including checking the levels of the progesterone hormone. You can also refer to the above progesterone level chart.

If low levels of progesterone are suspected, you should get tested before conceiving. Signs of low progesterone levels include:

  • Irregular menstrual periods
  • The use of certain medications for various medical conditions
  • A lack of physical exercise, etc.

What Are Normal Hcg Values And Rise

  • Blood hCG under 5 mIU/ml: Negative. Not pregnant
  • Blood hCG between 5-25 mIU/ml: “Equivocal”. Maybe pregnant, maybe not. Repeat test in a couple of days
  • Blood hCG over 25 mIU/ml: You are pregnant!
  • One single hCG reading is not enough to make a clear diagnosis. Several hCG tests 2 or more days apart give a more accurate assessment of the situation.
  • The blood hCG levels should not be used to date a pregnancy since these numbers can vary so widely.
  • For postmenopausal women, an hCG level up to 14 mIU/ml can be considered normal.
  • In a study of 20 patients in the first 40 days of pregnancy, the hCG concentration rose by at least 66 percent every 48 hours in 85 percent of viable IUPs but still, 15 percent of viable pregnancies had a rate of hCG rise less than this threshold.
  • An increase of > =35% in 48 hours can still be considered normal
  • hCG levels are best checked based on ovulation/fertilization day because the day of the last period can vary.

Changes In The Hair Skin And Nails

Many women will experience changes in the physical appearance of their skin during pregnancy. Although most are temporary, some such as stretch marks can result in permanent changes.

What Role Does Oxytocin Play In Pregnancy

Though oxytocin is around throughout your pregnancy, this muscle-contracting hormone is mostly known for stimulating labor contractions. And if your labor is slow to progress, you might get a shot of Pitocin, the synthetic version of oxytocin, to help move things along. Once youve delivered, oxytocin helps to shrink the uterus down in size and move milk into the breasts.

What Role Does Hpl Play In Pregnancy

This hormone is produced by the placenta to adjust your bodys metabolism to feed your baby. Along with placental growth factor, it preps your breasts to breastfeed. This hormone helps make colostrum, which is the antibody-rich pre-milk that precedes actual breastmilk. In some women, hPL and placental growth factor are thought to lead to insulin resistance, resulting in gestational diabetes.

What You Need To Know About Your Hcg Levels:

  • As you get further along in pregnancy and the hCG level gets higher, the time it takes to double can increase to about every 96 hours.
  • Caution must be used in making too much of hCG numbers. A normal pregnancy may have low hCG levels and result in a perfectly healthy baby. The results from an ultrasound after 5 -6 weeks gestation are much more accurate than using hCG numbers.
  • An hCG level of less than 5 mIU/mL is considered negative for pregnancy, and anything above 25 mIU/mL is considered positive for pregnancy.
  • An hCG level between 6 and 24 mIU/mL is considered a grey area, and youll likely need to be retested to see if your levels rise to confirm a pregnancy.
  • The hCG hormone is measured in milli-international units per milliliter .
  • A transvaginal ultrasound should be able to show at least a gestational sac once the hCG levels have reached between 1,000 2,000 mIU/mL. Because levels can differentiate so much and conception dating can be wrong, a diagnosis should not be made by ultrasound findings until the hCG level has reached at least 2,000 mIU/mL.
  • A single reading is not enough information for most diagnoses. When there is a question regarding the health of the pregnancy, multiple testings of hCG done a couple of days apart give a more accurate assessment of the situation.
  • The hCG levels should not be used to date a pregnancy since these numbers can vary so widely.
  • How Do You Test Hcg Levels

    Pin on Petite Bebes

    HCG can be detected in either blood or urine. However, a blood test is more accurate because it can detect smaller amounts of hCG.

    There are two different types of blood tests to detect hCG:

    • A qualitative test detects if hCG is present in the blood. It doesnt specify the amount, just that there is hCG.
    • A quantitative test measures the amount of hCG present in the blood. The results are in milli-international units of hCG per milliliter of blood .

    An at-home pregnancy test will be positive if hCG is detected in your urine. A urine hCG test is performed by either peeing on a chemical strip or placing a drop of urine on a chemical strip. At-home urine tests typically require higher hCG levels to return a positive.

    Keep in mind a low hCG level doesnt diagnose anything. Its a tool to detect potential issues. If your healthcare provider is concerned about your hCG level, they will test your levels again in two or three days. Then, they will compare the results to get a better picture of whats going on with your pregnancy.

    What Do High Hcg Levels Mean

    Higher than average hCG levels may be an indicator that you are having twins. In rare cases, it can also be a sign of a molar pregnancy or down syndrome.
