Negative Pregnancy Tests – Introduction
Have you ever been a week late and started worrying that you were pregnant? If so you aren’t the only one because there are a lot of women find themselves in this situation every month
This condition could also really be very frustrating to all women who want to conceive. Having a late period or the absence of menstruation, you patiently wait for a week after your expected menstrual period is due, only to get a negative test result. It becomes disappointing for most women but with enough knowledge, you can understand why it happens and you will know the important things to be considered to have a successful pregnancy.
What is a pregnancy test?
A pregnancy test checks a woman’s urine or blood. The test detects the presence of a hormone called human chorionic gonadotropin (hCG). This hormone is made by the placenta and when human chorionic gonadotropin is present, it may indicate that a woman is pregnant.
Missed period and negative pregnancy result
Every woman’s body is unique; each woman ovulates at different period even though she wants to go by the whole 14 day rule. A repeatedly negative pregnancy test result when you missed your period means that you are not pregnant.
The timing of a positive pregnancy test depends on implantation. If you are pregnant then a urine pregnancy test is not expected to be positive until, at the very earliest, 3-4 days after implantation which is about 10 days after ovulation/fertilisation (4days prior to next menstrual period), and about 51 percent of pregnant women have a positive pregnancy test 2 days before the expected next period.
Reasons for late menstrual period
If you understand your menstrual cycle you will know that there is such a complicated series of events needed to get you egg cell ripe and in the right place at the right time; it’s not surprising that occasionally the body takes a while to complete this process. These series of events can lead to an elongated gap between periods.
There are times that you may have a month when you do not have enough oestrogen level to result ovulation. If you do not ovulate, you might still experience menstrual period but your basal body temperature will not change as it does on a regular cycle, temperature is necessary for the success of fertilisation.
Having a lowered oestrogen level may be caused by travelling, vigorous exercise, stress, illness or losing weight.
Other medical reasons
- Polycystic ovarian syndrome (PCOS) – An estimate of 10 percent of women suffers from this condition and a lot of them don’t know that they have this condition. This condition is mainly characterised by hormonal imbalances. Symptoms include body hair loss, acne, weight gain, pain in the area of your ovaries, and heavy or irregular periods.
- Menopause (or perimenopause) – This condition is not common to women who are in there child-bearing age. The average age for women to end their periods is around fifty though in severe cases it can begin in a women’s thirties or as late as sixty.
- You became pregnant, had a miscarriage and this caused your period to be late and the pregnancy test to be negative.
- Being stressed out, in an accident, or had some other medical problems.
There are many reasons your period can be a week late and this is not completely uncommon itself. A missed or delayed period can be very frustrating but is not an indicator of a decreased ability to get pregnant.
The best pregnancy test to know whether you are pregnant is to simply have another pregnancy test in a few days. If it is positive, congratulations! If it is negative, you are not pregnant. If you still don’t have you monthly period or if you have a medical history that causes concern, you can always consult your doctor and there are many courses of treatment.
After a negative pregnancy test, might I still be pregnant?
Yes. Most home pregnancy tests (HPTs) suggest women to take the test again in a few days or a week if the result is negative. Every woman’s body is unique; each woman ovulates at different period even though she wants to go by the whole 14 day rule. So, the accuracy of HPT results varies form woman to woman.
Pregnant with a negative pregnancy test
Other things that can also affect the accuracy of HPTs are when a woman gets false positive results when they test too early in the pregnancy. This means that the test says you are not pregnant when you are.
If your home pregnancy test is negative, test yourself again in a few days or one week. If you keep getting a negative result but feels that you are pregnant, try to talk with your doctor.
False negative pregnancy test
To avoid a false negative pregnancy test, there are certain things you need to consider when having the test. The urine you use must be from the first urination after getting up of the morning. Early morning urine has levels of hCG that are easier to detect therefore you are likely to get a more accurate result.If for some reason you cannot use the first morning urine you need to use urine that has been building in the bladder for four hours or more. Avoid over consumption of water before taking the test as it can dilute the hormone levels therefore raising the odds of a false result.
Pregnancy and Ovulation Test
Pregnancy test is different from ovulation/fertility test. A Pregnancy test kit is associated with the detection of hCG or human chorionic gonadotropin (This hormone can be detected in the mother’s urine or blood before the woman’s missed period). HCG is first detectable in the blood as early as 7-8 days after ovulation by very sensitive HCG assays (research assays). In real life, blood pregnancy tests will be positive (> 2 mIU/ml) by 10-11 days after LH surge.
Ovulation tests identify luteinizing hormone (LH) – an ovulation predictor. High levels of LH cause a woman to ovulate (egg bursts from the ovarian follicle – fertile period). Most women will ovulate within 24-36 hours after a short-lived LH surge inside her body; therefore detecting LH by a fertility test is an effective method in anticipating a fertile period.
How long after a positive ovulation test will you take a pregnancy test?
Once you have performed an ovulation test and reveal a positive result, you will need to have more sexual intercourse over the following days to increase the chances of conception. The best recommendation on when to take a pregnancy test and have an accurate result is to be patient for at least until the first day when your period normally begins or until you have missed your monthly menstrual period. Otherwise you may test too soon and receive an inaccurate result that makes you more frustrated.
To increase your chances, simply test for ovulation first and then as soon as you have a positive result, have an intercourse with your partner over the next several days. Try and forget all about becoming pregnant and just be patient. If you think your period did not arrive on your expected date then think about taking a pregnancy test. This may not be the greatest advice to hear, but it really is the best way to have an accurate result regarding pregnancy.
