Fertile mucus question

Rachel
Okay so I have stretchy and watery cm yesterday with a tinge of pink. I assumed my fertile days were starting. I'm on cycle day 12 now and I have completely dried up and my opks are negative. Could I have ovulated super early and just caught the end of it? Last cycle was 80 days long and I knew when I ovulated because my opks were coming back positive. I was at my mom's all weekend so I didn't really pay attention to my Cm. My opks are barely showing a second line. What could this mean?
