Knowing your menstrual cycle — Physical changes to look for
Counting the days of your cycle can tell you how long your cycles are and whether or not they are regular, but the most reliable way to monitor changes in your fertility is by paying attention to clues from your body. Changes in your cervical mucus, basal body temperature and the position of your cervix can help you follow your cycle from start to finish. Some women chart all of these changes carefully to either increase or reduce their chances of becoming pregnant. Some women follow their cycles to know when to expect their periods, or to feel more in tune with their bodies. Mucus from your cervix changes throughout your cycle in response to hormonal changes. It’s a good marker of where you are in your cycle and checking your cervical mucus is quick, easy and reliable. Some women produce more mucus than others and may be able to see the mucus in their underwear. Others may need to feel the entrance of their vagina for it – use your fingertips or toilet paper. You can check your mucus at any time during the day. At the beginning of your cycle, when oestrogen levels are low, you won’t have much mucus at all. This dryness means you are relatively infertile. This is usually just after your period, but if you have a short cycle, it may be at the same time as your period and therefore difficult to monitor.
