Started period on 6-11-09, 4 days later fatty white tissue came out while using restroom about the size of my thumb was not covered in bloody just look like fatty tissue during surgery. This period was heavier than normal large blood clots and so on. Cramps normal, but i did have horrible back pain that came on quickly while at the grocery store the day before this weird tissue thing. Just brushed it off thought maybe i had been doing to much that day and or just thought it was pms stuff. Last month (May) was a week late started on the 11th. took preg. test that was negative. Little history i did have surgery on ovaries in OCT/07 on both ovaries to remove cyst. Have been on reg. monthly cycle since surgery every 28-30 days, except for the month of may/09.
