Thyroid

Dijana
So after having the merina in for almost 3 years. I had it removed in March so my husband and I are currently ttc and I went and had my hormone blood test. All my hormones appear to getting in normal ranges which is a first time ever. Previous struggle with pcos. My only down fall on this is that my thyroid is sluggish (which had never been the case). How can I correct this naturally and how will this affect my ttc plans?
