Thyroid effecting my fertility

Ok so I have under active thyroid which is an auto immune and chronic fatigue. It makes me ill a lot and I've been told by a lot of doctors that it's probably effecting my fertility, and that if I ever get pregnant there's a high risk of miscarriage or a still birth. I'm don't children right now but I know I want them within the next 10 years and I'm really feeling crap at the idea of not being able to. Does anyone on here suffer with a similar problem/ thyroid problem, and if you do, have you found pregnancy/ fertily okay? I'm a bit worried 😔😔
