Yes, I felt this way too, and now I am 6 weeks pregnant with my 2nd. I would HIGHLY reccommend educating yourself. Besides my Zofran for nausea, these books brought me so much comfort during my pregnancy! The 2 books I read cover to cover throughout my entire pregnancy was "What to Expect When You're Expecting" AND "You're Pregnancy Week by Week"

Anytime I had a weird symptom or concern, I just read about it and it put me at ease. Also, a good obgyn will help you and childbirth classes later on down the road will help too. You usually take them through your hospital. Good Luck and relax!!
www.babycenter.com is also a good resource, but I recommend the books first.
I also took a child physcology course at TCC specifically infants and toddlers and I learned SOO much! It really helped me with understanding parenting, discipline, growth and development stages as well. There are also great books that can help you with this such as "What to Expect the First Year".
