So sick to my stomach

Paula • Married I have four kids by previous relationship and hubby and I want one together but it`s not as easy as before
So I'm only five dpo and I'm so sick to my stomach that I can't move with out getting sick it feels just like the morning sickness I had with my son is it to early for me to be getting morning sickness if I'm pregnant the only thing I can keep down are saltine crackers and ginger ale
