Amenorrhea or absence of menstruation is often a symptom of pregnancy, especially in women of regular cycle. However, the absence of a period may be due to mere irregularities in the menstrual cycle. If you suspect that you have a pregnancy, consult your gynecologist for confirmation. There are different types of pregnancy tests with high reliability. One of the first symptoms of pregnancy for most pregnant women is amenorrhea, ie., the absence of menstruation.

In general, women with regular cycles are able to detect if they are pregnant more easily than women who have a more irregular ovulation. However, not having your period, does not mean you are pregnant.

Menstrual cycles usually occur about every 28 days, although they vary from one woman to another. In addition, the menstrual cycle is changing over the life of a woman, so that sometimes can go ahead and others falling behind.

Some factors that influence this irregularity can be sudden changes in weight, work or family stress or hormonal imbalance.

Other times, she may be pregnant and not know it can present losses, similar to menstruation, which coincide with the period. This is known as implantation bleeding and occurs when the fertilized egg attaches to the uterine wall.

If you suspect you are pregnant, you should make your first appointment with a gynecologist to confirm the pregnancy. The doctor will monitor and control of gestation. Also, check whether the woman has a complication such as hypertension, preeclampsia, placenta previa, which could indicate a high risk pregnancy.

However, if the woman goes through a period of high stress, very irregular and this rule has some loss, visiting the gynecologist is a must.

There are several tests to confirm the pregnancy and the pregnancy test , urine test, blood test and ultrasound.

Using a urine test or a blood test doctor can detect the presence of the hormone human chorionic gonadotropin (HCG). This hormone is responsible to secrete progesterone and estrogen, and appears ten days after conception.

In any case, the most reliable test for pregnancy diagnosis is by ultrasound, with which also confirmed the existence of one or more embryos. This test involves no risk to the woman or to the embryo, in case of pregnancy.
