confused? positive or no?

Erin • Mommy to 2 boys. 💙💙 trying for #3.
Okay...so I'm usually good at picking out other girls' positive OPKs. But me? Not so much. So I thought yesterday's were VERY CLOSE to being positive. But then today's strips are lighter. So maybe yesterday was my positive? Or maybe I haven't even reached a positive yet at all? Help?
