Believe me, mara, you are not alone. I've definitely had a major spike in anxiety throughout the beginning of this pregnancy. I've not been pregnant before, so I don't know what I'd be like if it'd been easy, but I can imagine it'd feel less fragile than it does now.
The good news is, I had my first OB appointment this AM and saw a beautiful baby measuring 9 weeks. We will get a blood test in a week and will know in a couple whether we have a boy or girl on our hands. The excitement will probably take me through the first week, then I imagine the nerves and disbelief will kick back in until our 13 week ultrasound. So it goes...
