Welcome to BB Ashli
If its what you want and you are in a position to do it then go for it, but make sure you weigh up the pros and cons. I had my DD at 17 and i wouldnt change it for anything, i went back to TAFE for 1.5 yrs and i'm having another break to have DD#2. I think if its what you want then do it, with your endo it could take you some time to conceive anyway so in a way its best to get started now.
Good luck, feel free to add me to msn if ya wanna chat (cool_chicadee@hotmail.com)
