Irregular menstrual cycles can have various causes, ranging in severity from 'very minor' to 'life-threatening'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose irregular menstrual cycles, we could:
|Polycystic Ovary Syndrome||1%||Ruled out|
|Diabetes II||0%||Ruled out|
|Ovarian Cysts||0%||Ruled out|
Are your natural menstrual cycles irregular? In other words, does the cycle length and/or the amount/duration of bleeding vary significantly from cycle to cycle? Do not answer if you have been using hormonal birth control for over 6 months.
Possible responses:→ Don't know / used birth control for over 6 months
→ No, my cycles are usually quite similar/regular
→ Yes, I have occasional moderate cycle variations
