Re: Can synthroid/hypothyroid hurt my baby?
Synthroid should not hurt anything. Chemically, its the same stuff your body produces naturally so you are "not taking drugs" per se, but replacing hormones that your body is not getting enough of.
I would not want to go through a regulation process while being pregnant cause it can be stressful to you physically and emotionally and of course to the baby. It is probably wise to get your hormones adjusted correctly before conceiving.
As for your levels, you should get more tests done. You need to know your Free T3 and Free T4 scores to figure your course of action. A TSH test alone cannot do much for you. It does indicate there can be a problem, but it is not a final diagnostic tool.
As for your depression, it can very well be a nonfunctioning thyroid that is the root. T3 in your system is like a shot of "happy drug". When you have enough T3, you feel upbeat, clear, focused.....kinda like speed. When your body does not have enough hormone, depression and fogginess are classic symptoms. I do not think hereditary has much to do with it.
I agree with your doc about getting regulated before conceiving but do not think it is mandatory at your level by any means. Your baby will not be slow and will not be short or anything like that.....at least I don't think that will be the case - you are BARELY hypo according to your TSH test alone and that number can fluctuate depending on the season, what you eat, stress, menstrual cycle, etc. I would start by retesting and including a full workup of TSH, Free T3, Free T4, Thyroid Antibodies and Total T3 and Thyroxine (Total T4). Once you have those numbers, you have a reference for future use and can decide what to do next.
