My boyfriend and I have been ttc for six months now, and I'm starting to think this month it worked. My last period was sept. 14, we had sex sept. 24 and oct. 1st. I've noticed I've had to pee much more frequently than usual. I don't want to spend a fortune on a bunch of pregnancy tests, what are the chances I am a mommytobe, and when should I test for best accuracy?
try anytime to help your curiousity but if you miss your period then that would be best. for me i don't know if i missed but all other factors added in i decided to take one well 2 and they both say yes
False negative readings can occur when testing is done too early. Quantitative blood tests and the most sensitive urine tests usually begin to detect hCG shortly after implantation, which can occur anywhere from 6 to 12 days after ovulation. hCG levels continue to rise through the first 20 weeks of pregnancy, so the chances of false test results diminish with time. Less sensitive urine tests and qualitative blood tests may not detect pregnancy until three or four days after implantation. Menstruation occurs on average 14 days after ovulation, so the likelihood of a false negative is low once a menstrual period is late. Ovulation may not occur at a predictable time in the menstrual cycle, however. A number of factors may cause an unexpectedly early or late ovulation, even for women with a history of regular menstrual cycles. Using ovulation predictor kits (OPKs), or charting the fertility signs of cervical mucus or basal body temperature give a more accurate idea of when to test than day-counting alone. The accuracy of a pregnancy test is most closely related to the day of ovulation, not of the act of intercourse or insemination that caused the pregnancy. It is normal for sperm to live up to five days in the fallopian tubes, waiting for ovulation to occur. It could take up to 12 further days for implantation to occur, meaning even the most sensitive pregnancy tests may give false negatives up to 17 days after the act that caused the pregnancy. Because some home pregnancy tests have high hCG detection thresholds (up to 100 mIU/mL), it may take an additional three or four days for hCG to rise to levels detectable by these tests ? meaning false negatives may occur up to three weeks after the act of intercourse or insemination that causes pregnancy.
hi mariah, you could be pregnant if you were exposed to unprotected sex somehow...wait for your next periods , if you have missed then take a test...for more accuracy you can take a blood test...if its negative then they are just irregular periods...
Accuracy claims can be somewhat misleading. Many home pregnancy tests typically maintain a 99 percent accuracy rate or better. The problem lies in the fact that these tests also imply that this accuracy could be expected if you take the test as early as the day of a missed period. A 2004 study published in The American Journal of Obstetrics and Gynecology by Dr. Laurence Cole and researchers at the University of New Mexico confirmed the deceptive claims of many of these early pregnancy tests. Cole explained that these claims are misleading due to the high degree of variation in the amount of hCG occuring in the urine on any given day after implantation occurs. Researchers found that for early detection of pregnancy, most tests were not sensitive enough to detect hCG on the first or second day after a missed period.The First Response? Early Result Instream Pregnancy Test detects in urine the hormone your body makes during pregnancy: (hCG human chorionic gonadotropin). The First Response Early Result In-stream Pregnancy Test is so sensitive that most women have enough hCG to be detected as early as 6 days sooner than the day of their missed period (5 days before day of expected period)#. The amount of pregnancy hormone increases as pregnancy progresses. In clinical testing, FIRST RESPONSE? detected the hormone levels in 62% of women 6 days before the day of missed period (5days before the day of expected period), in 78% of women 5 days before the day of missed period, in 87% of women 4 days before the day of missed period, in 98% of women 3 days before the day of missed period and 99% of women 2 days before their missed period.
Two different types of early pregnancy tests are available, urine and blood tests. Both tests will look for the pregnancy hormone, hCG. In today's world, many women use the urine test, or home pregnancy test (HPT), to discover whether they are pregnant or not. The best features of HPT's are that they don't cost a lot of money, they are easy to use, can be completed at home, and are completely private for the woman. The two blood tests for early pregnancy tests are performed by a health care provider. The first early pregnancy test is referred to a quantitative blood test. It measures the exact amount of hCG in the blood. This test can pick up very small amounts of hCG, making it a highly accurate test. The second early pregnancy test is called a qualitative hCG blood test. It gives a simple yes or no answer for the question of a pregnancy. This test is more like the urine test in regards to accuracy. Early pregnancy tests such as the blood test can pick up hCG much earlier in a pregnancy than urine tests can. A blood test can pick up the pregnancy hormone about 6 to 8 days after ovulation. The best accuracy time for the urine test is 2 weeks after ovulation. Some of the ultra sensitive urine tests can determine pregnancy as early as 6 days after conception, or one day after a missed period. Most early pregnancy home tests are very accurate. Depending on the use, a home pregnancy test will be 97% to 99% accurate. If an early pregnancy test is not done correctly at home, the test will be less accurate.
Yes, you can get a negative urine pregnancy test result during the early stages of pregnancy, the home tests are not 100% accurate. To test for pregnancy, the urine tests determine the amount of hCG (human chorionic gonadotropin), the hormone of pregnancy, that is in your urine. But they are not very sensitive tests. If there is enough hCG that the test can work to detect it, then the result is a positive test (you are pregnant). In very early pregnancy, until the level of hCG rises high enough for the test to react and give a positive result, you could be pregnant but get a negative test. To ensure the best results: Take the test in the morning, if possible, because your hCG (pregnancy hormone) levels are at it's highest, don't drink a lot of fluids before taking the test because it will dilute your urine and can affect the results Take the test no more than 1 day before expected period. Although some tests say that you can see results up to 5 days before your missed period, the percentage of accuracy is very low. Urinate for as long as possible on the foam-like strip. Check the results during the exact window of time suggested by the instructions of the pregnancy test.
