hi everyone,
I was told by my gyn that i had endrometrosis in my bowel tract only about 16 years ago. i had laser sugery done back then to remove it. for the last year or so i have been having brown spotting about 10 days before my period and if my husband and i have sex around that time i will bleed after but by the next day it stops. not sure whats going on if its the endro back or if im having a hormone problem going on, any suggestions would be greatly apperciated. thank you
