Endometriosis and ovarian cysts

I was just wondering if anyone has had endo and cysts on their ovaries and can offer any advice? My doc believes these are the reasons for the symptoms I have been getting - eg painful sex, painful periods, painful ovulation and general stabbing pains in my pelvic region. I am paying for a private pelvic ultrasound next week as I refuse to wait months for the NHS to fit me in, and am hoping everything is working as it should! Had my implant removed 3 months ago and this is when the symptoms started. If anyone could share their stories? And maybe shed some light on how long it takes to concieve having these conditions that would be great? I'm 26 and generally healthy.
