Late bfp?

Anyone end up implanting later than they expected and didnt end up getting a bfp until after 12dpo with minimal symptoms?? Every month I think its the month but im 11dpo right now all negatives, I have the worst oily skin ever and the past 2 days ive been having some pulling sensations every now and then and just a fuller feeling like before period shows but I never start early.. anyone ever experience this???
