Can't I ever be a mommy!! 😔

I am trying to do everything right, calculating dates, my ovulation, making love everyday and making it super frustrating and boring too! The place where I live there are no opk's available! So I do not know as to exactly what day am I ovulating! Now the confusion is that I get the egg white discharge just nine days past AF.. So does that mean I ovulate before the 14 th day of my cycle?? I need help because I always have been getting a BFN!! 😔 am so sad! Can't put it in words!
