Question

what is the major problem of irregular periods for a girl who is not in a relationship

Answer 1

The irregular period is the same whether in or not in a relationship. Are you asking because of fear of getting pregnant?

In any case you should always take condoms when having sex, it is to avoid getting pregnant but also to avoid to get diseases.

Irregular periods??...well that's a very common issue with most of the girls. Do you smoke??........i read somewhere that too much smoking causes some temporary hormonal imbalance at times and that may result in irregular periods.........drinking less water and unhealthy eating habits may also cause it.
