Every healthy woman can have an unovulatory cycle. If this occurs once or twice a year, you probably have no reason to worry. But if you've already been taking your basal body temperature and checking the other indicators of fertility (e.g. cervical mucus) for several cycles, and OvuFriend has never marked ovulation on your chart (When will OvuFriend mark that ovulation has occurred on my chart?), or always marks it with a dotted line (OvuFriend has marked the ovulation on my chart with a dotted line, what does it mean?), you should consult your doctor. He or she may want to monitor your cycle to check if you're ovulating.
The most frequent causes of unovulatory cycles are a hormonal imbalance, which may be caused by severe stress, an excessively intense workout, an extremely inappropriate diet, abnomalies caused by polycystic ovary syndrome (a quite frequent cause of unovulatory cycles), thyroid diseases and hyperprolactinaemia. Only a gynecologist, after carrying out the right examinations (e.g. ultrasound scanning, hormone blood test) and thoroughly reviewing your history, may be able to pinpoint the exact cause of unovulatory cycles. Your doctor will then determine the best treatment method. Often the right pharmacological treatment can quickly restore hormonal balance and ovulation.
