It is a frequent thing to have irregular periods between your cycle at older age particularly around 35 years. Women older than 35 years can have 28 days cycle in their first month and an interval of 30 to 40 days in the second month. A change in menstrual period for women of this age can indicate a pre menopause and there is nothing really to worry about.

If after two weeks you are still late on your period and your pregnancy test is still negative then you might be suffering from some health issues. A woman can miss her period due to numerous factors and being pregnant is not the only reason.

  • Poor eating habits: A woman’s body needs a balance of healthy nutrients and vitamins to maintain a regular menstrual cycle. If the diet is too rich or too poor, the menstrual cycle will be affected. Poor eating habits or disorders such as bulimia or anorexia can cause irregular menstrual cycles.

  • Stress: stress can lead to hypothalamic amenorrhea which is a type of missed menstrual period, the hypothalamus part of the brain is in charge of regulating a lot of hormones associated with menstrual period. This section of the brain is highly affected by stress thereby causing you to miss your period.

  • Medications: some medications can make a woman experience late or irregular periods. Such medications can include thyroid medications, chemotherapy drugs, birth prevention pills and so on.

The most common cause is the use of contraceptives. Even if the use of birth control pills is stopped, some time will still be taken before regular menstrual period resumes and until it becomes regular, women are still susceptible to late menstrual periods and negative pregnancy tests.

  • Ectopic pregnancy: this is very rare but sometimes an ectopic pregnancy can occur and produce a negative test result. An ectopic pregnancy is usually called a tubal pregnancy, this is when the fertilized egg attaches itself somewhere else and not in the uterus, HCG levels are lower than normal in this kind of pregnancy.

  • Excessive exercise: an exercise is a vital element of a healthy way of life but doing it excessively can be damaging to the body. If you are taking intense routine of exercises, your menstrual period might be delayed.

  • Low hormone levels: low pregnancy hormone levels can bring about both late period and negative pregnancy test result. A woman’s cycle vary, if you think you may have conceived and missed a period, you should wait for some days and do a retest. You should talk to your doctor to rule out complications if you continue to miss your menstrual period.

  • Breastfeeding: the act of breastfeeding brings about irregular menstrual cycle. For the new mothers, regular periods may take a while to get back on track. It may seem like they are skipping monthly cycles altogether instead. Several of them often experience late periods while others may not get to see their period for a very long time. This variation in periods is as a result of the high levels of prolactin present in the mother’s body. Prolactin is a hormone that helps in producing breast milk, it also restrain female hormones associated with the menstrual cycle.

The duration and rate of feeding can also have an effect on the menstrual period, if the baby is passing through a growth process and in the event starts feeding more, then the monthly cycle gets altered.

  • Weight changes: either weight gain or loss can cause a late period. Changes in weight affect ovulation and throw your cycle off the balance.

  • Uterine abnormalities: physical causes of delayed periods can include uterine abnormalities. Uterine structural problems such as scar tissue or other growths can induce menstrual irregularities. This may involve issues like the development of polyps, cysts, fibroid or endometriosis.

  • PCOS: medical conditions like PCOS or polycystic ovarian syndrome can cause late periods. In this condition, the normal menstrual cycle does not occur as a result of hormonal imbalance. The hormonal fluctuation causes ovulation to stop thereby causing delayed periods or completely missed menstrual periods.

  • LUFS: LUFS stands for luteinizing un-ruptured follicle syndrome. Fundamentally, your ovaries develop a follicle that is meant to release an egg, but it never does. This means that your body thinks the egg has been released. You get a normal ovulatory pattern and your luteal phase remains the same but still get a negative pregnancy test. You can’t diagnose this yourself, you need to see a specialist who will do ultrasounds around ovulation and check for abnormalities.

If a woman is of childbearing age and experiences typical pregnancy symptoms along with a missed period and negative pregnancy test, the case could be a false negative.


A false negative refers to a pregnancy test that shows the negative result implying not pregnant. Though, the woman experiences all the common symptoms of early pregnancy. This can be very frightening and annoying for women who are trying to get pregnant and perplexing for women not trying to conceive but experiencing pregnancy symptoms.

There is always a chance of false negative pregnancy so you do not need to get upset. Some of the causes of a false negative pregnancy test are stated below:

  • Wrong timing: timing is very essential to detect the presence of HCG, pregnancy test taken at the wrong time of the day will cause a false negative. It is better to test when with the most concentrated urine that is your early morning urine as it guarantees a more accurate result.
  • Not following instructions clearly: following the instructions stated with the pregnancy test is essential. You not following might lead to false results.
  • Lower sensitivity of the test strip: all pregnancy tests are not produced equally, some strips might be quite sensitive to HCG than others. Pregnancy test strips with lower sensitivity do not always detect HCG levels earlier in pregnancy. Choose a well known brand and repeat the test a few more times if necessary.
  • Expired pregnancy test: pregnancy kits expire due to the fact that they come with a useful life. When the chemical components for detecting HCG levels are no longer effective, the test won’t work thereby giving inaccurate results. To prevent a false negative, do not use a pregnancy test kit that is too close to expiration. It is important to note that pregnancy test kits usually have a useful life of two to three years.


Pregnancy is measured from the first day of your last period. Pregnancy tests should be taken at least fourteen days following conception, at that point you will be four weeks pregnant.

Your body starts to produce HCG when you become pregnant and it will be detectable with your blood and urine sample. Taking the pregnancy test at home should be carried out with the first urine sample as it is very concentrated.

You can also take pregnancy test asides from a late period when you experience the following symptoms:

  • Food aversions: when you get pregnant, you are often not attracted to certain foods you used to enjoy. This might be a side effect of rapidly increasing amounts of estrogen.
  • Morning sickness: nausea and getting the urge to throw up frequently, especially in the morning.
  • Spotting: this could be as a result of implantation bleeding, miscarriage or ectopic pregnancy.
  • Breast tenderness: sensitive swollen breasts are caused by the rising levels of hormones. This may feel like what you experience prior to your period.

There are many various reasons for getting a negative pregnancy test, you may be passing through some lifestyle issues, the best thing to do about a late menstrual period is to make an appointment with your doctor as he or she will be able to determine what is really wrong.
