In the first 2 weeks of pregnancy, women experience symptoms like light spotting, breast soreness, mood swings, nausea, bloating, etc. These symptoms are found due to a rise in human chorionic gonadotropin (hCG), which also helps in getting confirmation whether the implantation was successful or not.

The hormone hCG is important because, while home pregnancy tests work by measuring levels of hCG in a woman’s urine. hCG levels increase by 50% every day within one day of implantations. After 11-14 days of implantation, the hCG levels are very high, which starts showing pregnancy symptoms. So, women experiencing those symptoms may have a positive pregnancy report.

Every mother becomes excited about their pregnancy report. They are curious to know the following steps. The best, you need to take export advice regarding the body changes and the required step which need to take. The time for the process following implantation may vary. The hCG amount increase in the body by double fold. Some women may face little complications due to implantation. Proper care should be taken.
4 to 5 days under care should be advised by most of the doctors. The hCG cannot be detected immediately after implantation. For the indication of the hormone, hCG may take a little longer, a maximum of a week.

But, sometimes hCG levels can vary, so a pregnancy test may not always be accurate at this early stage.
Beyond confirming to the body that pregnancy has occurred, this hormone also helps in maintaining the endometrium. During the second trimester, however, the placenta develops completely and maintains the endometrium without any help. So there the women’s hCG levels drop.

Why Does HCG Rise So Long After Implantation?

The presence of hCG in urine and blood confirms pregnancy. It also helps in fetal growth. It determines whether the body is experiencing an ectopic pregnancy or miscarriage. If hCG levels increase more than 5 million International units per milliliters (mIU/ml) then it shows typical pregnancy.

When a non-viable egg implants in the uterus, they start secreting the hCG hormone, which occurs during the first trimester. Human chorionic gonadotropin is also known as beta-human chorionic gonadotropin(b-hCG) is a well-known hormone that is discussed and has several roles during pregnancy.

Most of the pregnancy hormones increase at the beginning of the pregnancy and continue the rise throughout the pregnancy period, but hCG doesn’t follow the same pattern. In the first several weeks of pregnancy, hCG levels double their concentration within every 29-53 hours. Almost after 8-10 weeks, it gradually begins to fall and then stops progressing. Both high and low, hCG levels indicate pregnancy. High hCG levels indicate a body experiencing a normal pregnancy. This happens because of the doubling of levels attaining the peak having 90-100000 mIU/ml.

Low hCG levels indicate a body experiencing early pregnancy, miscarriages, blighted ovum, and ectopic pregnancy. A low measured gestational age can be a severe mistake for the low hCG levels. It is more likely in cases where women do not have a normal menstrual cycle or not ovulating within 4 days. Sometimes, the high hCG levels may also result in twins or triplets which can only be confirmed through scans and by doctors. Whereas a little low than average hCG levels may result in down syndrome.


The increasing and decreasing levels of hCG and its roles in forming the endometrial line of the uterus and sometimes resulting in borderline pregnancy made this hormone an essential pregnancy hormone. During the early stages, the presence of hCG in urine can be known by the strong odor due to early pregnancy. This confirms women that her body is experiencing pregnancy and it turns into happy news. At the very early stage i.e. within 1-2 days of implantation pregnancy can’t be assured it may give a wrong report. So to get an exact report of pregnancy we have to wait till 2 weeks of implantation of ovum in the uterus.

Then after the hCG drops other regulating hormones like estrogen helps in the growth of the placenta and endometrium lining and the role of hCG completes. Implementation is the early stage of pregnancy and to hold on to it avoiding miscarriages hCG growth continues till the second trimester until the endometrium is completely taken over by the placenta for its maturation.
