Hi Jullchae...
A chemical pregnancy occurs when a fertilized egg does not implant into the uterine wall. If a pregnancy test is taken just at the right time it will be positive, however, when a repeat test is taken several days later it will be negative. A chemical pregnancy leaves the couple to cope with the difficult news of thinking they were pregnant when in reality they are miscarrying. However, majority of women who have a chemical pregnancy never know they are pregnant before they miscarry and begin what they think is their normal menstrual cycle.
Signs and Symptoms of a Chemical Pregnancy
Due to the fact that in a chemical pregnancy a fertilized egg does not implant into the uterus most women do not experience signs and symptoms of pregnancy (ie. tender breast, nausea, and / or fatigue). There are a few reports of women who have been pregnant in the past who state that they felt pregnant with their chemical pregnancy. There may be mild abdominal cramping as well as mild spotting just prior to what most women think is their normal menstrual cycle. The menstrual cycle usually begins on time or a few days late.
Chemical pregnancies are much more common than you might think. In fact, between 50% and 60% of all first-time pregnancies are thought to end in miscarriage C a large majority of which can be attributed to chemical pregnancies.
The difference between a chemical pregnancy and most other forms of miscarriage is that many women dont even realize that they have experienced one. This is because the vast majority of chemical pregnancies occur within the initial six weeks of pregnancy, when most typical pregnancy symptoms are not yet present, meaning that women is unlikely to take a pregnancy test.
Of course, with ongoing developments in pregnancy test sensitivity, women are becoming increasingly able to detect a pregnancy early on C as early as 3 days before a predicted period. As a result, it is likely that more women will begin detecting chemical pregnancies.
What Causes a Chemical Pregnancy?
Determining the reason for a chemical pregnancy can be difficult, however, there are a few known causes, such as:
Chromosome Abnormality: Chromosomal abnormalities are by far the most common cause of a chemical pregnancy, and are present at the time of conception, preventing the baby from forming properly. As a result, a miscarriage occurs.
Uterine Abnormalities: Abnormalities in the uterus, such as the presence of uterine fibroids, can interfere with implantation, leading to a chemical pregnancy.
Hormonal Deficiency: Women with luteal phase defects and other hormone deficiencies have difficulty maintaining a pregnancy due to a lack of hormones. As a result, the body experiences a miscarriage.
Chemical pregnancies are primarily diagnosed by confirming the presence of pregnancy through a pregnancy blood test. Once a pregnancy has been confirmed, your health care provider will monitor your hCG levels to ensure that your pregnancy is moving along smoothly. If there is a sudden decrease in your hCG levels, this may signal a miscarriage.
If these levels drop, an ultrasound will likely be performed to detect any signs of life in the uterus. If a chemical pregnancy has occurred, no embryo will be seen and no heartbeat will be heard.
I hope the above info helps becos I believe this is wat happen to me
