- This increase, or “surge” in LH, triggers ovulation, which is the release of an egg from your ovaries and the most fertile time of your cycle. The FIRST RESPONSE™ Ovulation Test Kit detects the LH surge, which precedes ovulation by 24-36 hours. Your two most fertile days begin with the LH surge. If you have intercourse within the next 24-36 hours of your surge, you will maximize your chances of becoming pregnant.

- Pregnancy tests with a sensitivity of 20 mIU/ml are more sensitive than tests with 50 to 100 mIU/ml. Test brands will display how sensitive their tests are using mIU as the standard unit of measure. Test sensitivity equates with early-detection-and the lower the number, the sooner a test can detect pregnancy. The most sensitive pregnancy tests can detect hCG levels at as low as 20 mIU-or at around 8 days following implantation of the egg.

Pregnancy Q&As Both blood and urine pregnancy tests check for the presence of a chemical called human chorionic gonadotropin, which is produced during a pregnancy. Waiting two weeks post conception (one the first day of a missed period) is recommended, but positive results can be detected as early as one week after conception. After a pregnancy has been detected by a blood or urine test, your doctor will request an ultrasound to confirm that a live embryo is present. Ultrasounds can first be seen at five weeks pregnancy and an embryo and heart beat can be detected by six weeks.

First Response Early Result Pregnancy Test, 3 Pack (Packaging & Test Design May Vary) I have used FRER's since 2007 when I found out I was pregnant with my first child. Here I am, in 2014, and I just got my big fat positive last night at...wait for it... SIX DAYS BEFORE MY MISSED PERIOD!!!!! I even took the test in the early evening, so I was definitely not expecting it to be positive at all. Sure enough, 30 seconds into testing, I see a faint, yet very visible pink line next to the darker test line.

SUCCESS RATES never mattered more 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 HCG injection or LH surge. In general, the HCG level will double every 2-3 days in early pregnancy. 85% of normal pregnancies will have the HCG level double every 72 hours. HCG levels peak at about 8-10 weeks of pregnancy and then decline, remaining at lower levels for the rest of the pregnancy. There is a large variation in a normal HCG level for any given time in pregnancy.

Are You Really Pregnant? The Truth About Early Pregnancy Tests These super-sensitive tests claim to identify a pregnancy a full week before a missed period, but embryos can fully implant (and start producing hCG) at different times. So, even if you're using the most sensitive test, your embryo may not produce a positive pregnancy test right away. In fact, it may take several days. For all of my pregnancies, I tested negative until two days after my period was due.

- High sensitivity tests are able to detect early pregnancy, when the HCG concentration in urine reaches 20-25 mIU/ml. There are also extra-sensitive 10mIU tests, but most women still prefer the first ones. They are reported to be more stable. Implantation usually occurs on the 7-10th day after ovulation. Still, you should take into account that the level of the HCG-hormone doesn’t reach the expected mark right away. It is growing gradually, increasing every 24-48 hours.
