Does no LH surge mean pregnancy?
A negative LH test does not mean that you’re not fertile, or that ovulation will not occur. This only means that no LH surge has been detected at the time you tested, so it is encouraged to keep testing. You may need to test more often, 2-3 times a day to catch the surge.

Does LH always surge before ovulation?
The LH surge begins around 36 hours before ovulation. Once the egg is released, it survives for about 24 hours, after which time the fertile window is over. Because the period of fertility is so short, it is important to keep track of it when trying to conceive, and noting the timing of the LH surge can help.
