What is the difference?
kamilacbronx posted:
Hello.I am concerned about my menstrual cycle. For over 13 years, I have experienced a difference in my period.I have experienced that when my period starts, it lasts for 3 days. Recently, my period started on July 11-24.This time it did not last a few days.Many doctors have told me that everything is normal. What can be done about this?
Joel Bernstien, MD responded:
Unpredictable bleeding can be a sign that you are not ovulating. There are specific tests your doctor can perform to see if you are or are not ovulating. IF you are trying to conceive, this is important information for you to know, as ovulation is a key component to conception.
kamilacbronx replied to Joel Bernstien, MD's response:
Thank you for your feedback.There is another question i would like to know.What are some of the tests that I would need in order to determine the reason(s) that I may not be ovulation? Another question I have is,which doctor would be able to perform theses tests?
Joel Bernstien, MD replied to kamilacbronx's response:
First your doctor needs to figure out if you are or are not ovulating. There are a few other lab tests done that may be able to find reasons why you are not ovulating if that is the case. Most of the time there is not a specific reason. I think an OBGYN is a good starting point for the evaluation. Different doctors do their evaluations differently, so I do not want to list specific tests here.

The most common reason a woman does not ovulate... by far... is obesity. The addition estrogen from the fatty tissues in the body lead to a "miscommunication" between the brain and the ovaries with regards to making and releasing an egg. Losing as little as 5-10% of ones body weight can often lead to regular ovulation and thus regular menstrual cycles.
