What can cause late, but a negative pregnancy test?

In some cases where a woman has a late period but a negative pregnancy test, she is really pregnant. This may be due to low hormone levels or defective testing. In other cases, the woman's time may be delayed or grinned for other reasons. These may include stress, illness or medicines.

There are several things that can cause a woman to miss her period but lead to a negative pregnancy test. The woman should not automatically conclude that she is not pregnant because she can be. Domestic pregnancy tests determine the concept of hormone detection called human chorionic gonadotropin or HCG. The sensitivity of the tests may vary and some require a greater presence of HCG in female urine than others.

If a woman performs a test near conception and uses a pregnancy test that is not very sensitive, it may indicate that she is not pregnant when she is really. Although it is relatively rare, it is possible for a woman to get a negative test result when it sees ectopic pregnancy. To that mIt can happen because even if her body produces HCG, she can do so at drastically lower levels that if she was in the middle of normal pregnancy.

Sometimes a negative pregnancy test is the result of impatience. It can be very important to follow the instructions on the packaging. Lower HCG levels can take longer detection. In general, there is a number of time in which results should be caused. Some women discard the test prematurely that they have received a negative result when the positive appears to be displayed later.

by using a pregnancy test can also bring false results. Somewhere on the test packaging should be the expiration date or "preferably before" the date. Women should avoid the use of devices after this time, as they may be unreliable.

There may be cases where a late period, but a negative pregnancy test does not include a pregnant woman. In many cases this type is confusedTo the result that a woman is experiencing great stress. Stress may have numerous effects on the body and for women one of them is delayed menstruation.

Some diseases may cause a woman to miss her period. The first example is thyroid conditions, as they often affect the balance of hormones of the body, which can affect the menstrual cycle of the woman. In addition, some drugs, especially those that are considered to be a control of contraception, may also have this effect. Irregularity may occur when a woman starts or ends treatment.
