Going crazy, you feel me?

I tested at 7 & 8 Dpo with FRER and saw vvfl both times. Retested today at 11DPO and nothing other than the indent lines being horrible on the tests themselves. I strangely had semi- bad cramps on and off all day today and thought FOR SURE period will be here any minute, because normally it would soon follow cramps like that that radiate to my back. Here I am and nothing not even spotting. Is this implantation? Should I just count myself out already... I have one more test for tomorrow. I sometimes wish the period would just come already if I’m not actually pregnant
