I m 26 yr old married women, my periods are irregular from past 7-8 month after the marriage, and from past 3-4 months once i have heavy flow and next?

Not ovulating: Some women naturally have irregular periods. This is usually caused by infrequent (not regular) ovulation. The longer you go between periods, the thicker the lining builds. When you finally do have your menses it can be heavy and long. Periods can become irregular if you've recently gained weight. BCPs can keep your menses regular. If you're trying to conceive then you may need fertility meds.
