Baby is almost here

Amy
Went to Dr today and was told baby is ready. I'm scared because I've only gained. 10 pounds. Am worried baby is going to be small. It's not that I didn't try to gain I've just had a lot of IBS. Sorry if it's too much fyi. My Dr said she wishes I would have gained more but I've had NO CRAVINGS AT ALL.... And work 2 jobs. Can anyone help with some input on my issue. Ty in advance.
