Sorry that things aren't going well for you Jo. I hate that you're having problems with the DH and your health as well. The good thing is that you have figured out the Hypothyroid and are now getting treatment. It is such a common diagnosis in my field of work and has great outcomes when treated with Synthroid, Levothyroxine, etc. It is very easy to manage once they find your correct dosage.
I am trying to relax and not worry too much with the pregnancy. I just get worried when I see all the ladies that go in for scans and find out they had missed miscarriages, etc. I have not had any complications so far so I guess I shouldn't worry so much.
