2 1/2 years.

So back in 2017 I found out I was pregnant but I didn’t think I was bc I’m irregular so I just figured it didn’t come one month but one day I felt nauseous over something so I decided to see & was positive but then a month later I had a miscarriage so then on I didn’t plan to try try I just let it be if it happens it happens but since I haven’t got pregnant never use protection. Then I found out I have Graves’ disease but my doctor said I can still get pregnant but still haven’t now I’m actually ttc but nothing ? Has anyone been through this or anything similar?
