If your period is one to two weeks late, and you still are getting negative pregnancy tests, a visit to your gynecologist for a pregnancy blood test is recommended. If your periods are frequently irregular, talk to your provider about when they'd like you to call.
There are many reasons your period could be late other than pregnancy. Stress, illness, and changes in weight or nutrition can all affect your menstrual cycle. If you're taking hormonal birth control or took emergency contraception, that can also change your period.
If a person misses a period and is not pregnant, it could be due to situational factors such as increased stress, intense exercise, starting new hormonal birth control, or experiencing sudden weight changes.
A late period can be delayed for about 5 days to a maximum of 1 to 2 months. A delayed period that lasts for longer than 3 months can be a sign of amenorhea, or lack of menstruation. In these cases, of pregnancy has been rules out, the underlying cause should be investigated by a gynecologist.
Test too early and the amount of hCG in your urine isn't detectable. As many as 9 out of 15 women will get a false negative until seven or eight weeks of pregnancy.
The most common reason for a late period and a negative pregnancy test is that your period is simply delayed and you're not pregnant. Having one or two irregular cycles a year is not unusual and does not mean there is something wrong. Reasons your period might be late include: Breastfeeding.
The tests work by detecting certain levels of human chorionic gonadotropin (hCG) in your urine. It's possible to get a false negative result. If you don't follow the directions accurately or you take the test too early, you might not have enough hCG built up to get a positive result.
The level of hCG continues to increase throughout pregnancy and doubles after 2-3 days. To get a positive pregnancy test, most women will have to wait 5-10 days after their period was due. Some may detect pregnancy earlier becuase hCG accumulates at different rates for different women.
"Low hCG levels may represent a very early pregnancy or a pregnancy that is ending in miscarriage," says Dr. Lang. Other causes include blighted ovum (the fertilized egg fails to develop properly) and ectopic pregnancy (the embryo implanted somewhere outside of the uterus—usually the fallopian tube).
High levels of stress or anxiety can cause irregular menstrual periods, which can sometimes be mistaken as a symptom of pregnancy. Nausea and vomiting, heightened sensitivity to smells, breast soreness, fatigue, frequent urination, constipation—these may be signs that you are “pregnant”.
Menstrual irregularities are common. Some people worry that they are pregnant or have a medical condition if they miss their period, but many other factors can contribute to a delay. Hormonal imbalances, stress, and weight loss, for example, can all play a role.
Yes, you may have a missed period for many reasons other than pregnancy. The reasons why you miss your period for a month may include stress, low body weight, obesity, polycystic ovary syndrome (PCOS), use of birth control, certain chronic diseases, early perimenopause, and thyroid issues.
A late period can be caused by being under or overweight, changes in birth control, and pregnancy. If it has been more than 30 days since your last period, you should take a pregnancy test. If you're pregnancy test is negative and your period hasn't arrived, see a doctor.

Don't Drink A Lot Of Water Before Taking The Test
Diluted urine tends to also have diluted hCG levels which can skew the test results. Take a test when you naturally need to pee. This way, you'll avoid diluting your hCG level and getting a false 'Not Pregnant' result.
The TORCH panel test is used to help diagnose infections that could harm the unborn baby during pregnancy. TORCH is an acronym of the 5 infections covered in the screening: Toxoplasmosis. This infection is caused by a parasite commonly picked up from cat stools.
Confusingly, when levels of hCG are too high, they can also interfere with pregnancy test results. This is why, interestingly, being pregnant with twins can sometimes cause a false-negative pregnancy test.
A borderline result is generated by some assays when the hCG level is between 5 and 25 mIU/mL. Samples reported as borderline are considered indeterminate, and clinicians should request a repeat test within 48 to 72 hours or obtain a quantitative serum hCG.
That said, hCG levels vary from person to person and pregnancy to pregnancy, so hCG levels are not definitive to determine a twin pregnancy. Some people have high hCG levels and only give birth to one baby; others have exceptionally low hCG levels and give birth to multiples.
HCG is only produced after an embryo has implanted in your uterine wall, which is why it's crucial to wait until the first day of a missed period or 21 days after unprotected sex before you take a pregnancy test.
Even if you're pregnant, your hCG levels may still be too low to be detectable in your urine. This is more common if you test before your period is due, but it can also happen right around the time of your missed period.
