I've been using the Clearblue digital OPK for the past two months... Last month I got a smiley 4 days after I started testing. I'm on day 7 this month and still no smiley. I am have sore boobs and some bloating like I already ovulated. I track with glow and with ovia. Glow keeps pushing my most fertile day forward. Ovia pushed my fertile window back and is telling my fertile window has likely closed for the month?? I'm so confused. Was it possible that I did ovulate and the test didn't pick it up? Or maybe I just didn't ovulate this month?
