symptom spotting

I know it's too early to tell or really even have any symptoms but I'm currently 3dpo since ovulation, this would be my first child so I know nothing about early pregnancy other than a day by day guide I saw on a different post which was helpful but I'm feeding into everything that might be a symptom. I'm pretty intune with my body and usually don't get cramps.. af isn't due until 2/28-3/1 but I've had small-medium strength cramps very day since BD... is this just all in my mind?
