Hey I'm Nikkie. I'm 3 weeks pregnant, an have thee worst morning sickness, headaches, light cramping, an no sex drive. Tired 24/7 and crabby towards everybody.. The day after I conceived, I started getting these signs. Is that normal?!? My due date is Sept. 25th. I'm always hungry, but can't eat cuz' I get sick to my stomach. What will help with this?
