Today we found out our little one is a boy! We're extremely happy,but I'm afraid of his weight. Today I'm 19W5D,gained 9lbs so far,and he's weighing 15oz. His heartbeat is 163. My due date is 2/28,but because of his weight the tech said it should be 2/18. This is my first pregnancy. I tend not to overeat,and I'm constantly walking the dog. I see the dr next week to discuss details,but should I be worried about anything?
