Hi.. There are multiple factors that are the reason for delayed menstruation.. Apart from the pregnancy and PCOD few other causes such as infection, thyroid problems, anaemia, poor nutrition, excess stress and many other factors can cause delay in periods.. A complete evaluation is needed to correct the problems of irregular periods.. Why don't you consult a specialist a gynaecologist who can really tell you what the problem may be...
Hi, thanx for your reply... i dont have any of the terms you have mentioned i got my blood test done and my doc told me i absolutely healthy... but im going to take your advice
