Depression: Is this normal?

Je

I am 11 weeks pregnant today after 2 miscarriages that ended in weeks 4 and 5. All was well at our first scan at 8 weeks and we have another this Monday. I have been so worried about miscarrying again that I haven’t been able to enjoy this pregnancy at all. I thought once I got to my second trimester I might be able to, but I have hypothyroidism and Hashimoto’s disease and am worried I will have a second trimester miscarriage due to low thyroid hormones. I am having them checked every 4 weeks and I am in range but not optimal; the thyroid groups I’m in tell me I need to be optimal and my doctor doesn’t seem to care. We are planning to announce after our scan this Monday if all is well and I’m just not excited about it. It’s been a stressful pregnancy also with a couple of scares. I do have depression and am on medication but I am starting to think I am more depressed, maybe due to hormones. I just don’t know what is normal or when I need to get a doctor involved.
