Thyroid

I'm getting married to the love of my life in November. We have been together for 3 years and I've wanted a baby for so long now. With his wishes we are waiting until marriage and I can't wait. I'm prepping my body to get healthy and everything. My one concern is I have thyroid disease and I heard that it can compliant getting pregnant fast. Please someone ease my mind. We don't have sex a lot as it is just because we both aren't the types that need it all the time, so I'm scared. Thyroid on top of that... I just want a baby finally.
