That's how I feel too! What did I do to get so lucky??? I think we feel like this because we are so greatful for this miracle!
Embrace it and enjoy the wonderful feeling. You're living your dream!!! !
Congrats on your little girl! I am 30 weeks and went for my 3D u/s and was told to take the tags off her clothes she is all girl. So yes in the future you may second guess if she is still a girl. From what I am told it is normal. Try not too much. Enjoy!
