Endometriosis & ttc

Hi ladies,
I just had a trans vaginal scan this morning & the sonographer said I have endometriosis but she will have to check again in 6 weeks to make sure it's not a cyst that has bled on itself.
I have been getting left pelvic pain for a few months now and it turns out the ovary concerned is my right one.
I was told my womb and left ovary are fine. 
Is anyone else going through this? 
I have no kids and had a chemical pg last year. 
I have a Drs appointment on Tuesday to discuss, but am really worried about my fertility as I'd love a big family. 
I'm 29 by the way
