This will be my third and my fiance's first. My two kids from my previous marriage are 8 and 6. I suppose since I was blissfully young I didn't realize how big of a life change having a baby is. I know now how stressful babies are and even how taxing being pregnant is. I'm worried about what I eat, how terrible it would be to miscarry, how this will effect our relationship. Is anyone else overwhelmed? I feel like I'm going crazy.
