The menstrual cycle and fertility relationship is important as the ovulation time determines the best time for conception.
Understanding your period cycle helps you learn more about your reproductive health and find the best time to get pregnant. Your cycle is a hormonal process that prepares your body for a possible pregnancy every month.
In this guide you will find out how the menstrual cycle works, how to identify your fertile days and when to seek medical advice.
What Is The Menstrual Cycle?
The menstrual cycle is the monthly process your body goes through to prepare for pregnancy. Day one is the first day of your period. And it goes on until the day before your next period starts.
Normal cycles can vary, the 28-day cycle is often used as an example. In adults, cycles of approximately 21–35 days are generally considered within the normal range.
Your cycle is controlled by hormones. They control the growth of the lining of your uterus, the release of an egg, and the changes that take place after ovulation.
The Menstrual Cycle: Four Phases
1. Menstrual Phase
This phase starts when your period begins. The lining of the uterus is shed . This leaves the body as menstrual bleeding .
Day 1 of your cycle is the first day of bleeding. Period length can vary. Bleeding usually lasts from 2 to 7 days.
2. Follicular Stage
The follicular phase starts on the first day of your period and lasts until ovulation. During this time follicle-stimulating hormone helps ovarian follicles grow and usually one follicle becomes dominant.
Oestrogen levels increase and the lining of the uterus becomes thick in case of a possible pregnancy.
3. Ovulation Stage
During ovulation, an ovary releases an egg. This usually happens about 14 days before the next period, but not always on Day 14.
The egg can usually be fertilised for up to about 12-24 hours after it is released. But sperm can survive in the reproductive tract for five days under good circumstances.
This creates a fertile window of around six days: the five days prior to ovulation plus the day of ovulation itself.
4. The luteal phase
The body produces more progesterone after ovulation to support the uterine lining. If pregnancy does not happen the levels of hormones fall and usually menstruation begins.
Hormonal changes help maintain the uterine lining if pregnancy occurs during early pregnancy.
How Does Your Menstrual Cycle Influence Fertility?
The connection between menstrual cycle and fertility is largely based on if and when ovulation happens.
Tracking your cycle can help you calculate your fertile window. You can keep track of your period dates, note changes in cervical mucus or use ovulation predictor kits to see if there is a rise in the luteinizing hormone.
If you notice clear, slippery cervical mucus, you could be approaching ovulation. But calendar calculations and symptoms are not 100 percent accurate in confirming ovulation.
If you are trying to get pregnant, having sex every one to two days during your estimated fertile window can improve your chances of conceiving.
