All About the Hormones
The Pearl Fertility Kit comes with 2 types of hormonal testing strips, testing levels of:
Follicle Stimulating Hormone (FSH)
Luteinizing Hormone (LH)
Tracking the levels of these hormones ensures you have the most accurate information about your fertile days.

The blue strip: FSH levels
FSH, or follicle stimulating hormone, is one of your most important hormones because it controls both menstrual cycle and ovulation. At the beginning of each cycle, FSH signals the ovaries to start follicle growth. Each follicle contains an egg, and the growing follicle then produces estrogen to prepare the uterus for pregnancy. Increased estrogen then leads to a sudden rise in LH- levels.
The pink strip: LH levels
LH, or luteinizing hormone, regulates the function of the ovaries. For the first two weeks of the menstrual cycle, LH stimulates the ovarian follicles that produce estrogen.
LH levels rise before ovulation:
Around day 14 of the cycle, LH levels rise, and ovarian follicles tear to release a mature egg from the ovary. This process is known as ovulation, the process by which the egg travels down the oviduct where it then can then be fertilized. If fertilization has taken place, LH causes progesterone levels to increase, and this hormone prepares the uterus for pregnancy. A balanced level of LH is key to causing and maintaining fertility.
By measuring LH levels, you can predict ovulation timing and fertility windows.
