I'm pregnant and my last period was in october the 16th. this is my 3rd pregnancy but this time i dont have any morning sickness, is this normal?

Can be: Many women never get sick during pregnancy & celebrate their luck. Their signal comes with loss of menses or they would not know. I would not consider it a cause for alarm/worry.

Yes.: Not having morning sickness is normal. Take prenatal vitamins. For the sake of your and your baby's health you should be under the care of a doctor. Wish you good health and a healthy baby!
