Pregnancy Symptom?

Laura
My husband and I are just starting to try to get pregnant. I've had some different things going on with my body and I want to know if these things are signs or just wishful thinking! 
I've had the worst heartburn I've ever had in my life most days. Another thing that is different is the last couple days, I've been itchy "down there" (wink wink), not swollen or any other symptoms. 
Has anyone heard of this during pregnancy or after conception? Thanks!
