Haven't had my first ultrasound but I'm very emotional and scared I'm not ready for this but at times I'm so excited for this journey with my partner. He is excited and already has a daughter and he has understood this stress before. I have always wanted a child, I'm just hoping I can be a wonderful mom. I've been working since I was 14, graduated high school and am now a full time student in college for almost 5 years. Just don't want the stress of life to hurt my little one or discourage me of being a good mother... feeling so scatter brained lately and could just use a ladies advice here.
