Worries now that I'm in my last month of pregnancy!

All the way through my pregnancy I haven't been worried about a thing. Just been wishing the months away. Now that I'm in my last month of pregnancy I'm worrying about things. First of all the birth and if I'll be able to handle the pain, if I'll be a good mom, I'm also worrying that he won't be healthy or a good weight when he's born even though I've had no issues all the way through. I just hope everything is okay. Is this just my anxiety or are these normal worries towards the end?
