When you miss your period or if your period is late, the most common concern is pregnancy. Taking a pregnancy test is the only way to know for sure if you are pregnant. Apart from pregnancy, many women have irregular periods from time to time — or throughout their lives. You might miss your period or your period may come earlier or later than usual or it may be much heavier or lighter than usual.
There are many reasons your menstrual cycle may change, including
- Non hormonal birth control — eg. IUDs can make your periods heavier
- Hormonal birth control such as the pill, injection, implants can make your periods lighter, make you miss your period or make it come later than usual.
- Various Medicines
- Over exercising
- Poor nutrition
- Sudden weight gain or weight loss
