An LH surge indicates that you have ovulated.
A Lh surge (known as the luteal surge) indicates ovulation, not pregnancy. The luteal surge causes the follicle to burst which releases the egg into the body cavity, it is then drawn into the fallopian tubule where fertilization occurs. An increase in HCG indicates pregnancy, HCG in blood and urine is the first outward sign of pregnancy.
The LH surge triggers the release of the egg. So, technically you cannot ovulate before you get the LH surge, but if you are testing with ovulation kits that measure the LH surge you can ovulate before you notice the LH surge. In order to detect ovulation, it is best to use a ovulation monitor that detects LH and estrogen levels because it is when the estrogen levels reach a certain threshold value that the LH surge occurs.
PMS symptoms often mimic early pregnancy symptoms. Woman get confused with this all the time. Progesterone is the cause of the symptoms and there is a surge of progesterone in every monthly cycle after ovulating. I would wait until you have missed your period to worry about pregnancy or not and if you do miss your period I would get a home pregnancy test to get the answers. :) Good Luck. ~Mom of four There is a chance the contraception has failed and you are pregnant but wait and see if your period comes first. >>i forgot to put in my question that i have already missed my period but had what i think is spotting for about 3 days? What do i do now? :S Take a pregnancy test or visit your family planning clinic or visit a doctor. There is not much else you can do. >>i took one home test but it came up negative...
Ovulation predictor kits, which measure the LH surge, are sensitive to the surge about 24 to 48 hours before ovulation. Sperm can live in the body for up to 72 hours, so even if the kit is showing a low surge, your chances of getting pregnant are higher if you have sex for the next few days than just waiting for the surge to be high.
Joules, a measure of electrical energy that is the product of Amperes, Volts, and Seconds. A typical surge might be 1000 volts, 10 amps, lasting 10 milliseconds - this would be 100 Joules. If a surge exceeds the number of Joules that the surge protector is rated for, the device will burn out and protection is lost.
Do you mean detection of the surge or the surge itself? Either is possible.If you have regular cycles, most likely you are surging regularly. One surges about 12-36 hrs before ovulation, and a surge always preceeds ovulation. It is possible to have a truncated surge without ovulating, such as when breatsfeeding or when under stress, but, for the most part, without regular surging, and thus regular ovulation, one does not get a regular period.As far as missing the detection, it is quite easy to miss. Often the surge is sharp and short. Thus if one is testing only one time per day near ovulation time, a surge may slip through the 24-hr crack. Once you know your body, it become easy to see when one is near a surge. At that point, if she tests 2x per day, it is much easier to catch.As far as no surge itself, it would signal an anaovulatory month.
