Baby question

Ka

Hey guys quick question & advice so I been of the pill over more then a year now, i haven’t gotten pregnant me & my boyfriend Tmi sorry guys do have sex occasionally since we live together now & i haven’t gotten pregnant yet, i also have endometriosis that shouldn’t be issue either right? Any advice why i haven’t gotten pregnant? any vitamins, advice you guys may have? I weigh 110lbs so that shouldn’t be an issue I’m not underweight or overweight. I have endometriosis like I said but that shouldn’t be an issue? Or could it be how can I start a healthy pregnancy or to get pregnant without treatment or anything like that thanks guys
