12 days late

Okay I'm 12 days late with all BFN's. :-( I started really bad cramping day before yesterday and started spotting bright pink yesterday and today. Still cramping mildly just don't know if I should retest or not. I hate the feeling of disappointment when there's just 1 line :( . But I'm also anxious to see what's going on I know I should wait to see if this is my period but ugh I want to test so bad
