What Is a Chemical Pregnancy? A chemical pregnancy is a very early pregnancy loss, usually occurring during the first 3 ½ to 5 weeks of your pregnancy. It is a real pregnancy. The term 'chemical' is used because the pregnancy can only be detected by a urine or blood test (chemistry) and cannot be seen on an ultrasound.

Chemical Pregnancy Authored by. Dr. Susan W. Trout. A chemical pregnancy is a pregnancy in which the woman tests positive for pregnancy but miscarries before anything can be seen in the uterus on ultrasound. Therefore the only evidence that she was ever pregnant is the chemical reaction that caused the pregnancy test to turn positive.

Pregnancy Pregnancy, also known as gravidity or gestation, is the time during which one or more offspring develops inside a woman. A multiple pregnancy involves more than one offspring, such as with twins. Pregnancy can occur by sexual intercourse or assisted reproductive technology. It usually lasts around 40 weeks from the last menstrual period (LMP) and ends in childbirth. This is just over 9 lunar months, where each month is about 29½ days.

- A chemical pregnancy is simply a miscarriage that occurs very early on in a woman’s pregnancy. Often, this is because a woman was able to obtain a positive determination of pregnancy from a test before her period typically occurs. As a result, the miscarriage will occur at the time of a woman’s period before a heartbeat is seen on an ultrasound. Part of the problem, when it comes to miscarriages that occur extremely early on, is the fact that there are many pregnancy tests on the market today that can detect pregnancy earlier than ever before.

Pregnancy Pregnancy is the period of time when a fetus develops inside a woman’s uterus and ends with the birth of the infant. Pregnancies typically involve a variety of clinical laboratory tests. The tests provide useful information from the time pregnancy is first considered through the initial days of the newborn's life.

Pregnancy: Ectopic/Tubal Pregnancy and Miscarriage Tubal pregnancy: A tubal pregnancy occurs after the fertilized egg implants itself in the fallopian tube and begins to develop. The egg however, cannot survive outside of the uterus because it will not get the nutrients it needs, nor have enough room (in the tube) to grow.

False Positive Pregnancy Test Blood tests can detect hCG at lower levels than urine tests, and therefore can detect a pregnancy earlier. Of course, it is possible for a woman to become pregnant, get a positive test result, and then miscarry. This is known as a chemical pregnancy. A positive hCG test result does not necessarily indicate a viable pregnancy.

Pregnancy and Teratogens However, your feedback is important to us. Teratogens are drugs, chemicals, or even infections that can cause abnormal fetal development. There are billions of potential teratogens, but only a few agents are proven to have teratogenic effects. These effects can result in a baby being born with a birth defect. Approximately 4 to 5 percent of birth defects are caused by exposure to a teratogen.
