My first OPK blinking high fertility!!

Sheena • Mommy of a daughter 4.5.10 & son 11.3.18
It's blinking!! I was so worried I wasn't ovulating so I picked this up a couple days ago! Glow said yesterday was the start to my fertility window but my OPK came back low.. Today it's saying High!! Yesterday we BD w PreSeed so I'm making sure tonight we do as well, every day up including my peak! I am so excited, every one please wish us luck!!
