Chances look good?

Paige

So today I am 12 days post ovulation and the past couple days I've had on and off headaches and short stabbing twinge pains on the sides of my breasts. I took a test on Monday at 10 days post ovulation it was negative. Trying to hold off at least until Friday when AF is supposed to show. Anyone think I still have pretty good chances and if my top to you signs are good?
