New to TTC and Glow - need help with OPK

Sarah
Hi ladies! I'm new to TTC and have some questions about OPKs. I bought the Clear Blue Advanced Digital one and got the blank circle my first day of testing. For the last 6 days I have gotten the blinking smiley face. According to Glow my peak day should have been on Tuesdsy. This is my first month off the pill so I'm not entirely sure what my regular cycle will be off the pill. Should I just keep testing until I get the not blinking smiley or does it look like maybe I'm not going to ovulate this month? Does that happen when you first come off the pill? I'm 31 and my DH is 33. I've been tracking my bbt but just realized I needed a thermometer that has two spaces after the decimal so I don't know how accurate it's been. I've also been trying to track my CM but don't really know what to look for. There are just so many possible descriptions and it's impossible to know exactly what I'm looking at! Would love any feedback or advice. Thanks in advance!
