Hi there, this is my first time on this site, and find it to be quite informative. However I still have some personal concerns which I would like clarified about my menstruation. Having started my periods at the age of 13, I always seemed to have them at irregular intervals, and on getting consulted I was always told by the doctors to get my weight under control and was also prescribed with Primolut N and Glucophage to bring my periods to a regular pattern (although I have been on the medications on and off based on different doctors suggestions, and my periods continued to be irregular). Now 27 years of age and married, did manage to shed off some weight at the age of 22 which helped to a certain extent as I now have my periods once a month but the interval between periods still varies each time including the flow of periods. Just to give an idea on the frequency (or infrequency for that matter!), for instance:- February 2012: Period started 20th - ended 25th- March 2012: Period started 31st - ended April 6th- May 2012: Period started 19th... likewise its always been hap-hazzard and what also worries me is the flow. During a proper period I have a moderate flow, but its as though if 2 times in a row I have a proper period the following month there will hardly be much bleeding...such that I dont even require a sanitary pad. Would this kind of infrequency, and blood flow affect my chances of conception in the near future? I have had an ultra sound test done, and test results show my uterus to be normal. Is there any cause for concern and should any precautions be taken, as I would like to start considering pregnancy soon? Would really appreciate a feedback on this...thanks.

Hello, Thank you for asking your question at Chat Doctor. I understand your concern. Long term history of menstrual irregularities can affect the chances of getting pregnant and need to be evaluated. Since you had been prescribed Primula N and gluconate before, I am thinking the first possibility for the irregularities in menstrual cycle as Polycystic ovarian syn Chat Doctor. It can lead to an ovulation/absent ovulation and lead to infertility. Maintaining a healthy weight is very important in treating PCs. There rare also medications available for treating PCs and helping ovulation. Other causes of irregular periods like thyroid disorders, prolactin levels also need to be checked recommend that you consult your doctor for further evaluation and appropriate management Hope I was able to help please feel free to add
