Since this is very early in your pregnancy I think your baby will be fine...speak to your doctor. Make sure you take a pre-natal vitamin because it's very important to get enough folic acid(B vitamin) to prevent Spina Bifida.

Fetus's are very resiliant, so try not to worry -stress insn't good for you or your baby. The more calm you are, the better for your baby. I was nervous too, but you're going to be fine and I pray you'll have a healthy baby. They're hard work, but the pleasure they give out weighs any trouble they put us through.
