11dpo spotting

I'm just looking for any ounce of hope that I could still get a BFP this month. AF would be due this Friday. We basically BD atleast every other day. After my static smiley (4/1/17) we BD 3 days in a row. Yesterday I had some brown blood (scant) only with wiping. Today I have some scant pink after urinating - not on undies just with wiping. Some twinges to my breasts. Otherwise no other signs.
