A period that comes every cycle at exactly the same time is not the norm. Of course cycles are irregular when they're first starting, as they're coming to an end, and around the times of pregnancy and changes to contraceptive methods. But even outside of those times, slight variations in timing and symptoms are common.

Should I be worried? No, you don't need to worry! It is normal 4 periods not to come on the same date every month – so don't be worried if this happens to you. This is because periods come in cycles – a cycle is from the first day of one period to the first day of the next period – and not strictly months.

Change in normal routine Changes in your normal routine can affect your hormones and cause your period to come early or late. For example, some research suggests that people who switch between day and night shifts, like nurses, often experience irregular periods. Switching time zones may have similar effects.

The consistency of menstrual blood varies both throughout the period and from one period to another. People may experience a heavy flow containing menstrual clots one month, and a lighter flow with no clots the next month. This variation is natural, and changes may occur due to diet and lifestyle factors.

If this happens every once in a while, it is likely no cause for concern, as variations in the menstrual cycle are common. Early periods often result from hormonal changes, especially during puberty and perimenopause. Many underlying medical conditions can also cause menstrual irregularities.
