Estrogen levels rise and fall twice during the menstrual cycle. Estrogen levels rise during the mid-follicular phase and then drop precipitously after ovulation. This is followed by a secondary rise in estrogen levels during the mid-luteal phase with a decrease at the end of the menstrual cycle.

Stage 1: Follicular phase = increasing estrogen Near the end of the first phase, estradiol levels peak, triggering the brain to release two hormones: a large surge of luteinizing hormone (LH), and a smaller surge of follicle stimulating hormone (FSH). This then triggers ovulation.

The ovulatory phase begins with a surge in luteinizing hormone and follicle-stimulating hormone levels. Luteinizing hormone stimulates egg release (ovulation), which usually occurs 16 to 32 hours after the surge begins. The estrogen level decreases during the surge, and the progesterone level starts to increase.

In the days before ovulation, there are two hormones that primarily run the show: estradiol (E2) and luteinizing hormone (LH). All about E2: A couple of days before ovulation during an average cycle, there is one growing, thriving follicle which houses the egg that your body will release during ovulation.

How the ovulation phase makes you feel. Estrogen and testosterone rise to peak levels, boosting the effects of the follicular phase. “Women feel more energy, more sex drive, and often they notice more cervical mucus,” Dr.

Irritability and emotional instability. Mood changes are also common during ovulation, and are mainly due to the hormonal changes that occur in the body.

Ovulation symptoms and signs to look out for Your cervical mucus becomes clearer and thinner with a more slippery consistency similar to that of egg whites. Your cervix softens and opens up. You may feel a slight twinge of pain or mild cramps in your lower abdomen. Your sex drive may increase.

A twinge of pain It’s possible to feel yourself ovulate, but many women don’t notice it. You might notice a slight pain in your side about halfway through your menstrual cycle. But if you’re trying to get pregnant, don’t wait for the twinge. That means your fertile window is soon closing.

the length of your menstrual cycle – ovulation usually occurs around 10 to 16 days before your period starts, so you may be able to work out when you’re likely to ovulate if you have a regular cycle. your cervical mucus – you may notice wetter, clearer and more slippery mucus around the time of ovulation.

Changes in body temperature Your basal body temperature rises by about 1°F or less during the 24-hour window after ovulation occurs. This is caused by the secretion of progesterone, the hormone which helps your uterine lining become spongy and thick in preparation for implantation of an embryo.

On average, a woman with a regular 28-day cycle ovulates on about the 14th day of each cycle. If a woman’s cycle is longer or shorter than 28 days, the predicted ovulation date is changed accordingly. For example, during a 24-day cycle (4 days shorter than the average), ovulation takes place on about the 10th day.
