So when should you test to find out if you are pregnant or not?
When you get pregnant, the pregnancy will produce a hormone called Human Chorionic Gonadotropin, also known as HCG. The earliest you can pick it up in the urine via a urine pregnancy test, is on the day you will have missed your first menses, cycle day 28 or so.
Period is late but test is negative?
A common problem women have is a late period with a negative pregnancy test. There are many reasons why this can happen.
First of all, many urine pregnancy tests are not completely reliable and they can show a negative result even if you are pregnant. Do repeat the test 3 to 5 days later and see what it shows. The HCG levels will be higher at that point and often the test will be positive if you are pregnant.
Another common reason is an early miscarriage. They are very common. Often it happens so early that the HCG levels never rise to the level where it can be picked up by the pregnancy test. Your next menstruation might then be a little early or late and will often be a little different than what you usually see. It is discouraging for this to happen but studies have shown that if you do experience an early miscarriage, most women will get pregnant very soon thereafter as well.
Finally, another common reason for a late period is that you did not ovulate that month. That can happen even in women who normally have regular cycles. Stress or a recent illness may be the culprit. Often the delay in menses is accompanied by breast tenderness and bloating so you will actually feel pregnant.
Not getting pregnant
Remember that it can take a while to get pregnant. Many of the eggs you produce every month are not good ones and it can take many months for it to happen.
If you are having regular cycles and you are still not getting pregnant, let your health care provider know soon. Find out from them when they want to see you. The soonest is usually after 6 months of trying to become pregnant, but many health care providers wait up to 12 months.
If you are NOT having regular cycles, or if you cycles are very short or long, as we discussed earlier on, you are likely NOT ovulating, so see your doctor sooner to find out why and to determine if you are a candidate for a medicine which helps women ovulate, called Clomiphene citrate (Clomid).
If you have had gonorrhea, Chlamydia or pelvic inflammatory disease (PID), it might have caused a blockage in your tubes. Your health care provider can perform an HSG test which will determine the patentcy of your Fallopian tubes. A hysterosalpingogram, or HSG is an important test of female fertility potential.
The HSG test is a radiology procedure done in the radiology department of a hospital or outpatient radiology facility, it only takes 5 minutes to perform. This shows whether the fallopian tubes are open or blocked and whether a blockage is at the junction of the tube and uterus (proximal) or at the other end of the tube (distal).
