Questions before treatment

Endometriosis and the desire to have children

Hi, I had a laparoscopy in December and was diagnosed with grade 1 endometriosis and adenomyosis uteri. The tissue was removed and the fallopian tubes were permeable. We have been trying for 4 months but so far no pregnancy has occurred. My gynecologist won't issue a referral to a clinic until after 12 months. I am worried though that I am running out of time and the endometriosis will start to grow again. What would you recommend?
