Nerves, nerves, and more nerves.

Is it normal to get anxiety about becoming a mother 1-2 months prior to giving birth? I've been with my SO for more than seven years and our baby was planned and I've been super excited about being pregnant but now that it's actually getting closer I'm starting to feel very nervous. I have all these thoughts going through my head like, "Will I be a good mother?" "I'm 24, am I really ready?" Either way, I don't regret anything about becoming pregnant, I know it will be one of the best things that will happen in my life. I just can't control how I'm feeling and it may just be my hormones, but I'd feel so much better to know I'm not the only one who is having crazy thoughts like this...
