Irreguler periods could be due to many causes hormonal problems-P COD, thyroid, underweight etc. Observe your period cycle for few months, see the gap between periods, during periods the duration, flow. If it regularizes then you can relax but if problem persists consult gynecologist . Takecare </s>
