no you won't get morning sickness til at least 7 weeks pregnant. you could get nausous fromt he drop in progestrone/estrogen though

The egg has to implant for any symptoms related to pregnancy to start. This is at least 7-14 dpo. Some women might experiance this before a missed period, but for most women symptoms, especially nausea don't start till 6-8 weeks of pregnancy.
