How long for menstrual cycles to start coming regularly

Postby cherbrig » Sun May 20, 2007 12:13 pm

My 13 ½ year old daughter started having her period October 2006 at the age of 13. We keep track of her cycle on a calendar. But it never comes every 28 days. At times there will only be 15 days between periods. As well as times where there is 40 days between her periods. They always last exactly 7 days. And are heavy from the first day. She experiences heavy cramping, bloating and tenderness with each period. The only routine about her periods is the length and the cramping. When will they start coming on schedule. Mine were always every 28 days like clockwork, so was my mom, her sisters and her mother. Her pediatrician said that it should only take a few months for them to get regular. Could this be a sign of an underlying problem?

For some girls it can take upwards of 1-2 years before they become really regular. Normal cycle lengths can vary from 3 weeks to 2 months. I would not be concerned about her continued irregularity at this point.

I suspect that over time her periods will become more regular.

Best wishes.
