You know, I think it's so weird...maybe its because its my first baby...but I'm 18 weeks and besides the obvious (morning sickness, growing cramps, back pain etc) I don't feel pregnant. I see the sonogram pics and hear the heart beat but I haven't felt him or her move and I don't look any different...
