Day one of a woman’s cycle is the first day of menstrual bleeding or spotting, representing the start of a new cycle and another opportunity for conception to occur.
Each month, your body begins to prepare for ovulation – the release of an egg from your ovary, triggered by a rapid increase (surge) of Luteinizing Hormone (LH).
In the beginning days of your cycle, the LH levels in your body are low. This is considering your personal baseline level of LH, and every woman’s baseline level is unique.
As the cycle progresses, there is ultimately a rapid increase (surge) in LH that signals that the ovary is about to release an egg. This LH surge indicates that ovulation is about to occur, which begins your optimal 24-36 hour window to try to conceive.
During this 24-36 hour fertile window, the egg travels down the fallopian tube. If a sperm successfully fertilizes the egg, conception occurs.
Since every woman’s body and baseline hormone level is different, you can maximize your opportunity to conceive by establishing your body’s unique baseline and pinpointing your LH surge.
The FIRST RESPONSE™ Digital Ovulation Test uses your unique baseline hormone level to determine your personal LH surge – detecting your two best days to try to conceive.
