Your history shows abnormal and irregular cycle length and infertility
. The normal cycle length is 21 to 35 days. Polycystic ovarian syndrome
is the most common cause of abnormal menses and infertility. To diagnose this syndrome, ultrasound
scan is usually advised, which is then followed by hormonal
analysis, such as serum FSH and LH. Serum insulin level and fasting blood sugar are also helpful. I advise you to go for ultrasound pelvis examination first, and then for blood investigations.
