What is the Follicular Phase?

The follicular phase is the first half of your menstrual cycle, starting on the first day of your period and ending with ovulation. During this phase, follicles in your ovaries mature, with one eventually releasing an egg. Hormones like follicle-stimulating hormone (FSH) and estrogen play critical roles. Knowing the approximate dates of this phase helps determine your fertile window.

How Our Tool Helps You Track the Follicular Phase

Our Pregnancy Calculator & Ovulation Estimator offers valuable insights into the follicular phase, even without a specific "follicular phase calculator" function:

  • Ovulation Estimation: By inputting your cycle length and last period date, our tool estimates your ovulation day, marking the end of the follicular phase and the start of the luteal phase.
  • Fertile Window Prediction: The calculator identifies your fertile window – the days leading up to and including ovulation – when you are most likely to conceive. This window is directly related to the later part of the follicular phase.
  • Interactive Calendar: The six-month calendar visually displays your period days, fertile window, and estimated ovulation day, offering a clear picture of your cycle.
