I am a 25 year old female. 5'8" 155lbs with two children via c-section (2 years and 9 months) For the last 3-4 months I have had abnormal periods. One month it will be extremely heavy and last 7-10 days then the next month it will be very light and last only 3 days. In Aug. 2011, the first 3 days were very heavy and then i've been spotting off and on since 8/19/11. Today 9/4/11 I began cramping really bad to the point where it hurts to walk and if i do walk and go to sit down it hurts all the way into my back and the interior of my vagina. I have never experienced this type of pain before except for contractions during labor. If you could please help I would greatly appreciate it. Thank you
