(First Trimester) Is the world trying to make a newly pregnant woman completely paranoid?

~* Written from my perspective; pregnant for the first time, nervous, unsure what to expect and really hormonal; take these posts with a grain of salt please *~
The first week; Over the next four days, I tried to deal with all the things that I couldn’t have while pregnant and picked up a book that promised ‘277 stress free tips for pregnancy,’ but one of the first things that the book told me was that I couldn’t sleep on my back anymore, and that I needed to really think about my diet, protein, no junk food, etc. Here we go again, more, NO’s. I didn’t like the book anymore; every “no” caused me MORE stress, not less. Did I sleep on my back last night, did I kill my baby? This is madness! How do women deal with all of this? The final straw came when the book told me to avoid high altitude, I live in Denver at 1 mile high, and my love is hiking. Not just any hike, but I love to climb big mountains, and realized that I couldn’t hike a 14er this year, according to the book; this really made me sad. I had pictures in my head of being pregnant and still hiking; it’s something that calms me and puts me in a good head space. I needed to ask my doctor about this high altitude “no.”

On Friday, my 7 month pregnant friend Heather stopped by with her 1 year old cute as can be daughter ,Jillian, and I told her the good news, and cried some more on her shoulder as she hugged me. I told her my fears and she suggested I look forward to the milestones and things that I was excited about, maybe taking pregnancy photos, or feeling that baby move for the first time (which is again something that scares me because it’s a foreign feeling in my body). But then she mentioned that I couldn’t eat the turkey sandwich she brought for me because I couldn’t have lunch meat; and then  something about too much vitamin A will cause birth defects, (what the hell has vitamin A in it, I thought?). She cautioned me against using my homeopathy remedies, and said I should ask my doctor if I can take them. More; NO’s, and things I hadn't even considered.  AAAK!

The one thing that she said that did stick with me; that I think about every time my stomach ties in knots is that there is such a euphoria when the baby is born and placed on your chest, it’s the most wonderful feeling ever. So, I try to think of my baby being born, but November seems so very far away.

She also suggested I register online at thebabycenter.com; so on Saturday morning I got up and signed up, put in my day of last normal period and got my due date (something that I had done a zillion times on day 1). October 30th, A Halloween baby, I liked that. I started to read about the first few weeks of pregnancy and one of the things that thebabycenter.com suggested was to take another pregnancy test a few days after the positive test; to make sure an early miscarriage didn’t occur. That freaked me out! So I took the last remaining test that I had; waited 5 minutes and made Josh go check it “you’re still knocked up” he says; then thebabycenter.com said that sometimes it takes 10 minutes for the test to accurately read; so after 10 minutes I asked Josh to check it, he confirmed that I was still ‘knocked up again.’ At least that was good news, no miscarriage this week; do I need to take a test every week until the 2nd trimester? Do they just tell you these things to freak you out, I think so!

Then Josh brought me a small cup of coffee and cautioned me that I wasn’t supposed to have very much coffee or caffeine (the only caffeine I ever have is my 2 cups of coffee each morning). I grumbled to him that I didn’t want to hear from him what I couldn’t do, and sipped my 1 cup very slowly savoring it.
Someone please tell me what I CAN do?
