If there was no morning sickness through the first pregnancy could you have it your second?

It is possible to have morning sickness in a second pregnancy even if you did not experience it in your first pregnancy. Morning sickness is thought to be caused by a combination of hormonal and physical changes that occur during pregnancy, including increased levels of the hormone human chorionic gonadotropin (hCG), which is produced by the placenta. While some women experience morning sickness in their first pregnancy, others do not, and some women who do not experience morning sickness in their first pregnancy may experience it in a subsequent pregnancy. The severity and duration of morning sickness can also vary from one pregnancy to another, so even if you did not have severe morning sickness in your first pregnancy, you could have it in a second pregnancy.
