Af due today, will she come!?

So last three days I tested and got bfn. I am now 11/12 dpo and af is due. I had mild cramps earlier in the week, thick, heavy, milky discharge 4dpo. My nipples kills, seem slightly darker. I've been moody and eating everything in sight. Only dtd a couple times near ovulation which didnt result in full ejaculation. Really thought i was out until these symptoms started. Don't know what to think. My luthal phase is so short this month. :/ anyone dealing with the same thing?!?
