Progesterone is produced after ovulation by cells in the now empty egg follicle. If the egg is not fertilized and there is to be no pregnancy, the level of progesterone subsides causing the uterus to shed its lining. But some women s hormones are easily thrown off balance by changes in bodyweight or diet, excitement, stress or illness. And it may cause problems like irregular or missed periods. They usually occur during the two weeks prior to a period and may include bloatedness, breast soreness and swelling, fatigue and irritability.
Most women are somewhat aware of the constant internal murmur of their hormones.
If you have been menstruating for a few years you are likely to be familiar with your own rhythm. Your can probably tell when your period is about to begin. After your period the estrogen level starts to rise again and you may get a sudden renewal of energy and feel that you can tackle anything. It's a good idea to develop this ability to listen to your body. You can try to avoid stressful situations when you know you are likely to be grouchy or tired, and plan special events for days when you are likely to be full of energy.
