Fertile days: Do you know when they are?

DGP fertile days

The fertile days are when a woman is most fertile are around the middle of the cycle. The menstrual cycle consists of several physical and hormonal changes.

How is a woman’s menstrual cycle?

Not to be confused with menstruation, the menstrual cycle consists of various physical and hormonal changes. These affect the body and each month.

Approximately, a cycle can last between 23 and 35 days depending on the woman, but the length of the menstrual cycle varies in each woman.

The average frequency of a cycle is 28 days and serves to prepare the body for the possibility of a pregnancy. A good knowledge of the functioning of your body is essential and allows you to maximize your chances of getting pregnant.

Fertile days: What hormones are involved?

The hormones involved that regulate the menstrual cycle are:

  • Estrogens: Female sex hormones produced by the follicles of ovaries and reaching their peak in the days leading up to ovulation. The main function of estrogens is to regulate the menstrual cycle. It thickens the endometrium and fluidifies cervical mucus, a fluid that sperm must pass through to reach the egg and fertilize it.  This is a woman’s most fertile time and the best time to have sexual intercourse.
  • Progesterone: Progesterone is the other female sex hormone main. It is produced by the corpus luteum, which remains of the follicle after the release of the egg during ovulation. Its main task is to preserve the endometrium and optimize the implantation of a fertilized egg. The peak of progesterone is usually reached on day 21 of the menstrual cycle, about a week after ovulation.
  • FSH: FSH, a follicle-stimulating hormone, is produced by the pituitary gland in the brain. Its function is to mature the follicles of the ovary and also plays an important role in the onset of puberty. Your level rises again and favors ovulation before falling to a low level just before menstruation.
  • LH: LH, a luteinizing hormone, is also produced in the brain. Its task is to trigger ovulation and release the egg ready for the fertilization.

Different Phases

We can distinguish three phases: Follicular, Ovulatory and Luteal.

  • Follicular: This phase is part of the pre-ovulation cycle and lasts the first 10 to 16 days. Occurs on the first day of the period until ovulation.

Hormones: Estrogen levels rise just before ovulation when the ovary prepares to release an egg. FSH levels increase also during menstruation and descends a few days before ovulation, when it is important for the organism to select only one egg fertilization.

  • Ovulatory: On the 14th or 15th day of the cycle, the mature egg leaves the ovary and reaches the fallopian tubes. Past 12-24 hours, if not fertilized by a sperm, it will dissolve.

Hormones: Estrogen levels increase when the ovary is prepared to release an egg.

  • Lutea: The luteal phase, which lasts 14 days, occurs after the ovulation cycle. Produced just before menstruation, the woman may experience symptoms premenstrual as increased appetite, pimples, need to sleep more, bloating and oily hair.

Hormones: The follicle becomes a hormone-releasing structure endocrine called corpus luteum. This organism begins to produce progesterone, which is responsible for maturing the endometrium so that it can implantation (pregnancy) occurs.

And what about fertility?

The days when a woman is most fertile are around the middle of the cycle. In other words, day 14 of ovulation and provided the cycles are regular.

The fertility interval is established between the previous three days and the three days after day 14 of the cycle, when the probability of fertility is greater. The sperm can live 24 hours, so fertility can occur in anytime.

However, it is more reliable to do an ovulation test and check for changes in the vaginal mucus. When the mucus becomes clear, thick and elastic, it means that ovulation will soon be here. The ovulation period is the time when you and your partner should have more sex if you want to stay pregnant women.

It is also important to take into account the quality your partner’s sperm, which influences your ability to get pregnant.
