6dpo cramps. I have a question.

For the past couple of days I have suddenly felt nauseated. It happens suddenly. Then will go away. Today I am feeling menstrual like cramps. Isnt between 6-12dpo that implantation can happen. I'm trying to be positive in hopes that this may be my month. I want a lil one so bad. Antine else felt this at 6dpo and ended up with a BFP when it was time to test?
