People say that pregnancy is suppose to be one of the most exciting times in a woman's life. But for me,  it is the most nerve wrecking.  The thing that I look forward to the most at this stage, is my appointments with my doctor. It is at these meetings when affirmation of a heart beat makes me most excited.  I can just sit for minutes on end and listen to the heart beat of the child growing inside of me. I don't need to see photos and videos of fetal movement, just let me hear the heart beat.  This makes my day!!! Sadly, this feeling that everything is alright, lasts for about a week and then i'm on edge again, stressing that something might have gone wrong. I hate feeling so paranoid during what is suppose to be the happiest time of my life. I wonder, if this feeling that possess me is normal. It's not like i'm a first time mom. Is this healthy????
