Hate to buy another pregnancy test

Meagan

I was supposed to get my period on the 25th but ended up ovulating instead. I tested on the 5th and it was negative. And the past few days my boobs have been hurting like they usually do before a period. So should I wait it out and see if i get my period? Or just test? I just feel like it's a waste of money and a punch to the gut when I see that negative sign.
