hCG or the Human Chorionic Gonadotropin hormone is the indicator hormone and the placenta is responsible for its production. It is called so because its presence is proof that you are pregnant. It is the presence of this hormone that is checked in pregnancy tests. Claim Your 20 Free Pregnancy Tests – Click Here
The levels of hCG can be detected with ease after at least ten days of conception or fertilization in urine as well as in blood. In blood, it may also be detected earlier than ten days. Thus this hormone is the basis of blood pregnancy tests too. If hCG is present, it is a positive indicator of pregnancy.
Once the egg is fertilized and successfully implanted in the uterus, the hCG tends to rise rapidly. An increase is seen throughout the first three months of pregnancy. After 80 days, the level of this hormone is at its peak. Thus, if you have symptoms such as breast tenderness, vomiting, irregular spotting, pelvic pain, delayed period, and so on, you might be pregnant. You should immediately get a blood test done to check.
The reason why this hormone is so important is that it prepares the body for pregnancy. The normal corpus luteum is converted into pregnancy corpus luteum so as to aid the growth of the fetus in the body. Corpus luteum is a surface that produces hormones such as progesterone.
You should keep in mind that hCG is produced regardless of where the implantation occurs. For example, there is ectopic pregnancy in which the implantation occurs outside the uterus. Even in these cases the level of hCG is seen.
You should make sure you know your hCG levels throughout the first trimester of the pregnancy so as to be sure that the levels are increasing as they should. If you find that they are too high, you should talk to a doctor. It may indicate ovarian cancer, molar pregnancy, choriocarcinoma of the uterus and so on.
In the case of twin pregnancy and multiple pregnancy too, the levels of this hormone are high. That is why you should consult the doctor immediately if you find that the hCG levels are higher than what they should be to rule out any problems. To be sure that you are having twins or multiples, you could go for the beta hCG test.
In other circumstances you may see that the levels of the human chorionic gonadotropin hormone are going down instead of going up during the first trimester. This may indicate miscarriage. The levels must and should increase in the first three months and a decrease is not a very good sign at all. You may have already had a miscarriage or the levels may indicate that you might have a miscarriage soon.
Ectopic pregnancy is another possibility. What happens in this case is that the levels of hCG increase each day but not as much as they should. Ideally, the hCG levels must double every second or third day throughout the initial three months of pregnancy. If you are having an ectopic pregnancy, the levels may increase slightly but not enough.
You can track your hCG levels if you want or have them checked from time to time just to be sure that everything is normal. If there is a decrease, reaching the doctor on time may save you from a miscarriage. It is all about keeping track and staying alert at all times.
