About once a month, females who have gone through puberty will experience menstrual bleeding. This happens because the lining of the uterus has prepared itself for a possible pregnancy by becoming thicker and richer in blood vessels. If pregnancy does not occur, this thickened lining is shed, accompanied by bleeding. Bleeding usually lasts for 3-8 days. For most women, menstruation happens in a fairly regular, predictable pattern. The length of time from the first day of one period to the first day of the next period normally ranges from 21-35 days.<\/p>\n<p><strong>How does the menstrual cycle work?<\/strong><\/p>\n<p>The menstrual cycle is controlled by a complex orchestra of hormones, produced by two structures in the brain, the pituitary gland and the hypothalamus along with the ovaries. The menstrual cycle includes several phases. The exact timing of the phases of the cycle is a little bit different for every woman and can change over time.<\/p>\n<p>Cycle days (approximate) Events of the menstrual cycle<br \/>\nDays 1-5<br \/>\nThe first day of menstrual bleeding is considered Day 1 of the cycle.<\/p>\n<p>Your period can last anywhere from 3 to 8 days, but 5 days is average.<\/p>\n<p>Bleeding is usually heaviest on the first 2 days.<\/p>\n<p>Days 6-14<br \/>\nOnce the bleeding stops, the uterine lining (also called the endometrium) begins to prepare for the possibility of a pregnancy.<\/p>\n<p>The uterine lining becomes thicker and enriched in blood and nutrients.<\/p>\n<p>Day 14-25<br \/>\nSomewhere around day 14, an egg is released from one of the ovaries and begins its journey down the fallopian tubes to the uterus.<\/p>\n<p>If sperm are present in the fallopian tube at this time, fertilization can occur.<\/p>\n<p>In this case the fertilized egg will travel to the uterus and attempt to implant in the uterine wall.<\/p>\n<p>Days 25-28<br \/>\nIf the egg was not fertilized or implantation does not occur, hormonal changes signal the uterus to prepare to shed its lining, and the egg breaks down and is shed along with lining.<\/p>\n<p><strong>Knowing more about your menstrual cycle<\/strong><\/p>\n<p><em>Menstrual phase<\/em><\/p>\n<p>The menstrual phase is the first stage of the menstrual cycle. It\u2019s also when you get your period.\u00a0This phase starts when an egg from the previous cycle isn\u2019t fertilized. Because pregnancy hasn\u2019t taken place, levels of the hormones estrogen and progesterone drop.\u00a0The thickened lining of your uterus, which would support a pregnancy, is no longer needed, so it sheds through your vagina. During your period, you release a combination of blood, mucus, and tissue from your uterus.\u00a0You may have period symptoms like these:<\/p>\n<ul>\n<li>cramps<\/li>\n<li>tender breasts<\/li>\n<li>bloating<\/li>\n<li>mood swings<\/li>\n<li>irritability<\/li>\n<li>headaches<\/li>\n<li>tiredness<\/li>\n<li>low back pain<\/li>\n<\/ul>\n<p>On average, women are in the menstrual phase of their cycle for 3 to 7 days. Some women have longer periods than others.<\/p>\n<p><em>Follicular phase<\/em><\/p>\n<p>The follicular phase starts on the first day of your period (so there is some overlap with the menstrual phase) and ends when you ovulate.\u00a0It starts when the hypothalamus sends a signal to your pituitary gland to release follicle-stimulating hormone (FSH). This hormone stimulates your ovaries to produce around 5 to 20 small sacs called follicles. Each follicle contains an immature egg.\u00a0Only the healthiest egg will eventually mature. (On rare occasions, a woman may have two eggs mature.) The rest of the follicles will be reabsorbed into your body.\u00a0The maturing follicle sets off a surge in estrogen that thickens the lining of your uterus. This creates a nutrient-rich environment for an embryo to grow.\u00a0The average follicular phase lasts for about 16 days. It can range from 11 to 27 days, depending on your cycle.<\/p>\n<p><em>Ovulation phase<\/em><\/p>\n<p>Rising estrogen levels during the follicular phase trigger your pituitary gland to release luteinizing hormone (LH). This is what starts the process of ovulation.\u00a0Ovulation is when your ovary releases a mature egg. The egg travels down the fallopian tube toward the uterus to be fertilized by sperm.\u00a0The ovulation phase is the only time during your menstrual cycle when you can get pregnant. You can tell that you\u2019re ovulating by symptoms like these:<\/p>\n<ul>\n<li>a slight rise in basal body temperature<\/li>\n<li>thicker discharge that has the texture of egg whites<\/li>\n<li>Ovulation happens at around day 14 if you have a 28-day cycle \u2014 right in the middle of your menstrual cycle. It lasts about 24 hours. After a day, the egg will die or dissolve if it isn\u2019t fertilized.<\/li>\n<\/ul>\n<p><em>Luteal phase<\/em><\/p>\n<p>The luteal phase lasts for 11 to 17 days. The average length is 14 days. After the follicle releases its egg, it changes into the corpus luteum. This structure releases hormones, mainly progesterone and some estrogen. The rise in hormones keeps your uterine lining thick and ready for a fertilized egg to implant.\u00a0If you do get pregnant, your body will produce human chorionic gonadotropin (hCG). This is the hormone pregnancy tests detect. It helps maintain the corpus luteum and keeps the uterine lining thick. If you don\u2019t get pregnant, the corpus luteum will shrink away and be resorbed. This leads to decreased levels of estrogen and progesterone, which causes the onset of your period. The uterine lining will shed during your period. During this phase, if you don\u2019t get pregnant, you may experience symptoms of premenstrual syndrome (PMS). These include:<\/p>\n<ul>\n<li>bloating<\/li>\n<li>breast swelling, pain, or tenderness<\/li>\n<li>mood changes<\/li>\n<li>a headache<\/li>\n<li>weight gain<\/li>\n<li>changes in sexual desire<\/li>\n<li>food cravings<\/li>\n<li>trouble sleeping<\/li>\n<\/ul>\n<p>Your menstrual cycle can also change during certain times of your life. For example, it can get more irregular as you get close to menopause.<\/p>\n<p><strong>What you should know about getting pregnant?<\/strong><\/p>\n<p>Getting pregnant is all about timing, having sex at the right time. Ones menstrual cycle can give you clues about when your body is ready to start the process.<\/p>\n<p>The first step to getting pregnant is to learn the days when you&#8217;re most fertile. Most women have a 28-day menstrual cycle. That means you have about 6 days each month when you can get pregnant. That includes the day that one of your ovaries releases an egg, called ovulation, and the 5 days before. Having sex within that window is key.<\/p>\n<p><strong>How can I Chart my menstrual cycle using BBT?<\/strong><\/p>\n<p>Chart your menstrual cycle and record how long it lasts. Day 1 is the first day of your period. Since the length of your cycle can vary slightly from month to month, it&#8217;s best to keep track for a few months. Once you have an average, subtract 18 days from the length of your shortest cycle. This is the first day you&#8217;re likely to be fertile. Next, subtract 11 days from the length of your longest cycle. This is the last day you&#8217;re likely to be fertile. Having sex between those two dates will give you the best shot at getting pregnant.<\/p>\n<p>Take your Basal body temperature (BBT)<\/p>\n<p>This BBT is your temperature first thing in the morning. Just after you ovulate, it rises slightly &#8212; sometimes by less than a degree &#8212; and stays higher until your period starts. If you record your temperature every day, you can spot the subtle changes that mean one of your ovaries has released an egg. Take your temperature at the same time each morning. Always do it before you get out of bed. (To make it easier, keep the thermometer on your nightstand.) Even getting up to go to the bathroom can affect your body temperature. So can smoking, drinking, or getting a bad night&#8217;s sleep.<\/p>\n<p>Remember, your BBT won&#8217;t tell you exactly when you&#8217;ve ovulated, and it may take a couple of months before you start to see a pattern. You&#8217;re most likely to get pregnant 2 or 3 days before your ovary releases an egg, and then another 12 to 24 hours after that. When your temperature has spiked for 3 days, your chances of conceiving drop.<\/p>\n<h2>References<\/h2>\n<ol>\n<li>The National Health Service. <a href=\"https:\/\/www.nhs.uk\/conditions\/periods\/fertility-in-the-menstrual-cycle\/\">Fertility in the Menstrual cycle<\/a>.
