Does anyone know what I can do?

My husband and I really want to get pregnant. We've been trying for 5 months, we found out I have a dermoid tumor on my right overy.. The doctor suggested we have children before having it removed because it'll lower my chances of being able to have kids. Problem is the tumor stopped my periods, they gave me natural stuff to be taking to get them when I need to but said they wouldn't give any advice on what to do until we've been officially trying for a year. I'm very discouraged and was wondering if anyone's had to deal with this, and does anyone know of anything that could help?
​Sorry if this is just a stupid question
