Concerned

One thing about pregnancy that is both good and bad is baby books.  I have been given about five baby books from the doctor's office all about different things.  I've been reading through each of them and they give me some good information, but they also make me worry a little bit.  A few weeks ago all the baby books said that I should start to feel movements from the baby.  Well, it has been a few weeks and I have felt nothing.  I asked my mom and she said she felt movements at around 18 weeks too.  So, now I am 2 days from being 20 weeks and have still felt nothing.  I have been feeling really worried, wondering if my baby is still ok.  I've been fretting and thinking maybe I did something to the baby.  I finally called the doctor today to ask about it and they said everything should be fine.  They said some women don't even feel anything until 22 weeks.  It was comforting to hear that, but I'll still be relieved to have my appointment on Tuesday so I can see the baby moving and listen to its heartbeat.  It is interesting that I can care so much and worry about a tiny little person that I've never met.
