I am 22 years old and I had a tubal ligation May 4th, 2012, when I was 21. I have had one live vaginal birth (2009), and one abortion (2011). Prior to my tubal ligation I have always had a very predictable/regular menstrual cycle. It was almost always 28 days, but occasionally 27-29 days, and I had a pretty light to moderate flow with no dysmenorrhea. Since my sterilization I have had cycles ranging from 22-32 days, and I still do not have dysmenorrhea. My most recent cycle was 32 days and I menstruated for 1 day. Is this something that occurs often or is it something to be concerned about? I could find only find a handful of peer-reviewed articles on this and they stated that the results of their studies showed that there is no difference in menstrual abnormalities between women that have been sterilized compared to those that have not.View Thread
