Symptoms or not?

Jamie • My name is Jamie Samkowiak and my husbands name is Austin. We have been together for 8 years.
I am 7 dpo today. I started having extremely sore breast a couple days ago. My nipples are so sensitive I could die! I had dizzy spells at 6 dpo and cramping especially on my right side. I'm not sure if I'm having symptoms or making myself because I really want to be pregnant? Any suggestions. I was thinking about testing tomorrow at 8 dpo even tho I know it's early..
