Anyone here dealing with Thyroid issues and told not to get pregnant for a yr after taking the RAI pill or having a Thyroidectomy?

I just recently took the RAI pill a few weeks ago and will go to see my endocrinologist this week. I would like to try to have another child, but I feel like I have a few things slowing me down. I'll be 38 in Aug and waiting a yr would put me at 39 before I'm able to try again. 😌😔My 1st child didn't take much trying at all it took was one time and bam I was pregnant. It was an easy pregnancy. I know all aren't the same. Every pregnancy is different. I'm just worried about my age and thyroid problem. Just want to know if anyone else went through it and your stories if any. Thanks! 😁
