You are one of the lucky ones with no morning sickness, trust me, its no fun... I didn't had it my first pregnancy and my baby boy was and still is healthy, but with this one I did, and it wasnt pleasant... good luck on the rest of your pregnancy...
I'm 30w4d and never had morning sickness and my son is perfectly healthy and so am I. If your doctor doesn't address something, 9 times out of 10 what you hear is an old wives tale and not true
