do you feel the morning sickness come back at third semester?

Yes this is normal. Some pregnant women experienced morning sickness when near to due dates. The baby grows quite rapidly during the third trimester and uses minerals and vitamins in your body. This may sometimes make you feel nauseous. Just keep in mind that while occasional nausea is normal, you should go to see your doctor if it occurs too often and it is accompanies by frequent vomiting. http://www.newhealthadvisor.com/Third-Trimester-Nausea.html
