Don't be so scared...worrying will only make you feel more streesed and that's not good for you or baby! First pregnancies do not always end in miscarriage...there are many factors that contribute to a miscarriage. I had my first child (my son) when I was 3 months shy of my 20th birthday. He will be 12yrs old in December, stands as tall as my shoulder-height (I'm 5'11"), and is a football player. Yesterday, we found out we are finally expecting our second child estimatedly on May, 31st 2011. We are just thrilled!! Like a previous poster said, limit your caffiene intake....also, stay away from green tea, it inhibits your bodies absorbtion of folic acid (VERY, VERY important for baby to prevent neural defects!!), don't smoke or drink, take your prenatal vitamins, be careful with eating fish too, some have a high mercury content tuna is OK though, don't take cold meds without consulting your doctor because many of them contain alcohol. That's all I can think of right now...my mind has been sooo scattered lately, lol. If I think of anything else I'll let you know. OH, and look into the book "What to Expect When Your Expecting" it was my bible the first time around, so much so that when I gave birth I went out and got "What To Expect the First Year", and "What To Expect the Toddler Years"!!!
