ttc with endometriosis

Audriana
We've been ttc for close to three years.i had my lap in February and still no luck. I only have one ovary but I do ovulate every month and to no avail I'm not pregnant.Ive had a workup and all I was told was it was for unknown reasons since my endometriosis was not severe.Any ideas of what I can try next? I do use preseed
