My wife is facing problem for periods. Its almost 20 days up that she is not having periods. We have tried having pineapple,jaggery with sesame seeds,raw pappaya etc. Usually she gets periods on time and sometimes its 2-3 up but this time its high time. Since last couple of days she was having alot of work pressure which may be due to stress and also she has gained alot of weight in few months. Kindly suggest what should we do as we have not yet planned for having baby.
