Anyone with thyroid disease ttc or pregnant?

Heather • so blessed to have my 2 beautiful children!
I just found out I have hypo thyroid in April and started synthroid. My levels are normal now. Anyone ttc with this and what has it been like for you. If you are pregnant, how long did it take ttc? And how are you handling your pregnancy. I miscarried in December before knowing this. Ttc since July. My cycles are still 23-27 days with spotting of 3-5 days prior to periods. I'm getting tired of being disappointed every month. I have a 5 year old and I had absolutely no problem with her pregnancy. Please share your experience if you have this.
