Bbt help/ does it look like I'm getting closer to Ovulating

What thermometer are you using? I used one from Walmart last month. Then I left it when we went on vacation last weekend so I bought a new one at target and kept using it so I didn't switch during this cycle. Seems like the Walmart bbt reads very low at times and I took my temp with it the other morning after using my target bbt and it is off. Does it look like I'm getting closer to ovulating? Cm has been really low this month compared to last. I keep having light cramping on the left. And I have gotten high fertility on my clear blue advance for 3 days. No peak smile yet. And last time I used it I got 8 days of blinking smile no peak.
