Ttc with endometriosis.

So back in Oct I went to see my obgyn . I was dignosed with endometriosis. endometriosis can cause dificulty in ttc. If not treated . Obgyn told me no big deal plenty of ways to get rid of it. 1 way is taking the pill witch I chose to do. So I have been taking the pill since Nov when my 1st period started. How long should I wait 2 stop taking the pill and ttc again . I'm just wanting so bad 4 a baby.
