Follicular phase

The follicular phase starts on the first day of the period and lasts until the third phase (ovulation).

What happens during the follicular phase?

During this time, follicle stimulating hormone (FSH) stimulates the egg cells in the ovaries to grow. At the beginning of each cycle, the body secretes FSH and encourages the ovaries to produce eggs.

What happens to the eggs?

Each egg grows in a fluid-filled sac called a follicle. The FSH stimulates a number of follicles to develop and start producing oestrogen. Levels are at their lowest on the very first day of the period but they start to increase moving forward as follicles grow.

One dominant egg matures and suppresses the rest and whilst this is happening, oestrogen works on thickening the uterine lining. Once the mature egg is released at ovulation, the empty follicle (the corpus luteum) releases progesterone (in a higher amount) and oestrogen (in a lower amount). Together, they work on making the uterus thick with appropriate nutrients and blood for a fertilised egg to grow.

How do you feel during this phase of the cycle?

Many will find they feel really good during the follicular phase. For me personally, I feel very driven and creative during this time. It is often referred to as your “happy” time of the month. When talking to Tracey Banks, MD, said: “Those two weeks are usually good compared to how you feel toward the end [of the cycle].”
