Your fertility is driven by your hormones. The image above illustrates a typical hormonal profile. Estrogen increases before ovulation in the follicular phase of the menstrual cycle. Progesterone is elevated after ovulation in the luteal phase.
Your body provides signals that tell you when each of these hormones is high.
Cervical fluid tells you about estrogen levels and your basal body temperature (BBT) tells you about progesterone. If you use ovulation prediction kits (OPKs) they tell you about Luteinizing Hormone (LH) which briefly peaks just before ovulation.
Fertility Friend connects these fertility signs to your own hormonal profile and creates a personalized fertility chart accurately displaying your fertile days and your ovulation date. You'll also get interpretations and analyses tailored to you.
The image below shows a zoomed in fertility chart with ovulation detected for the day before a temperature rise. The fertile days are the days before ovulation and the day of ovulation. Fertility Friend alerts you to those days using a visual signal, also shown below, to help you maximize your chances each cycle.
