TTC #2 and never knew opks would prove my calendar wrong

So this is my 2nd cycle of ttc for baby #2 and since I didn't really get to use opks last cycle, I decided to start using them religiously this cycle. I started the day after my period ended. So right around CD7. And now today, on CD10, I have an almost positive opk. I'm nearly there.

But according to glow's prediction, my predicted fertile window doesn't start for another 3 days. It's really cool to see how my body work this time around. So hopefully soon I can start my TWW

Good luck and baby dust to all of us TTC!!!
