Those with irregular menses, how do you conceive successfully? I find it difficult to know when do I exactly ovulate and my fertile period.

Alternatively, you might want to try to find out the root of your irregular periods. Below is the list that *could* be the cause: 1) ecessive weight loss or gain. Although low body weight is a common cause of missed or irregular periods, obesity also can cause menstrual problems. 2) Eating disorders, such as anorexia or bulimia. 3) Increased exercise 4) Emotional stress 5) Illness 6) Travelling When I was 22, I had long period of irregular period, and when I started taking things slow and relaxing a little more, eventually it slowly got "regulated"
