Don't know what to think...

Have any of you ladies who have recently conceived, had similar symptoms?  I am 2 days past due date of AF.  I have tender breasts, period like cramps, nausea and some spotting but not enough to use anything.  Could I be pregnant or is this just a light period.  I took a test at 10 dpo and 11 dpo both negative.  Spotting is a brown color sometimes and others bright pink
