1. You're not taking the Pill as regularly as you should.
The Pill takes a hold of your hormones, and forgetting more than three doses can lead to irregular spotting and bleeding, or really painful PMS symptoms. (BTW, things could get worse if the birth control pill you're taking isn't very suitable to your body.)
2. You're too stressed.
Stress is the most common cause of missed or late periods. You get your period through a complex hormononal balance. When you're stressed, your brain will release other hormones like cortisol (the fight or flight hormone) that will disrupt the balance, causing your period to be late, be more painful, or skip it entirely.
3. You drink too much coffee.
For some women, drinking coffee worsens the PMS symptoms like cramps, headaches, and mood swings. Caffeine increases tension, anxiety, and your stress hormones which then increase your blood pressure. When there's too much hormones in the body than necessary, the oxgyen supply in your brain is lowered hence suppressing your immune system.
5. You drink too much alcohol.
Too much booze can make your period irregular. Alcohol can temporarily increase your body's levels of estrogen and testosterone, which can disrupt the normal hormonal fluctuations that are needed for ovulation.
Alcohol also increases breast tenderness and lowers your blood sugar, which can make you more irritable and give you more headaches, anxiety, and fatigue.
6. You train too hard.
Rigorous exercise (like training for a marathon) can lead to hormonal imbalances which in turn will make your periods less frequent. Because training too hard uses a lot of energy, the body, in order to conserve energy, will shut down unnecessary functions. (Your period isn't vital to your body; it's for reproduction.)
Your period will return to normal months after you stop the strenuous activity.
Before we forget, this isn't an excuse to skip your workout. Exercise keeps your body healthy, boosts your mood, and alleviates dysmenorrhea by improving overall circulation.
7. You have an eating disorder.
If you're suffering from anorexia or bulimia, you're likely to not get your period. Extreme weight loss suppresses the release of hormones that are needed to maintain normal levels of estrogen. If your estrogen levels are too low, ovulation won't occur and your period will stop.
