Is a 35-45 day menstrual cycle normal?

1. Is the menstrual cycle 35-45 days normal?

The menstrual cycle is measured from the first day of menstruation to the first day of the next period. While the average menstrual cycle lasts 28 days, a normal cycle can range from 21 to 45 days. Therefore, menstrual cycles within this range are considered normal:

• Menstrual cycle 35 days
• Menstrual cycle 40 days
• Menstrual cycle 45 days
• Menstrual cycle fluctuations are 35 - 40 days

Large gaps between menstrual periods commonly occur in individuals who have recently had their period. Conversely, shorter and more regular cycles are typical for older women. Additionally, irregular menstrual cycles can be linked to the use of birth control pills or the placement of an IUD (Intrauterine Device).

4. What happens during ovulation?

Ovulation is the process in which an egg is released from the ovary. When menstruation begins, an egg develops and is subsequently released. After ovulation, the egg has a lifespan of approximately 24 hours.

Pregnancy occurs when sperm encounters and fertilizes the egg. Sperm can survive in the fallopian tubes for up to seven days after sexual intercourse.

In some cases, more than one egg may be released during ovulation. This can lead to the possibility of multiple sperm fertilizing the eggs, resulting in twins or triplets.

Women cannot become pregnant if they do not ovulate. Hormonal contraceptives, such as birth control pills and patches, can effectively prevent ovulation.

5. When is it easiest to conceive?

The best time to conceive is during ovulation, which is when a woman can get pregnant. While it can be challenging to pinpoint the exact day of ovulation, it generally occurs about 10 to 16 days before the start of the next menstrual period.

It's a common misconception that all women are fertile on day 14 of their menstrual cycle. This statement may apply to women with regular 28-day cycles, but it does not hold for those with shorter or longer cycles.
 

6. What type of vaginal discharge is considered normal?

Vaginal discharge varies throughout the menstrual cycle. Around the time of ovulation, it tends to become thinner and more stretchy, resembling raw egg whites. If you notice any unusual changes in the color of your discharge or detect a foul odor, it is important to consult a gynecologist for advice and treatment if necessary.
