My period came 3 days early and that changed my ovulation prediction for the previous month, leaving me to believe I missed my window :(. I decided to buy LH tests to better detect my fertile window. I’m now on CD 5 and took a test just to see and much to my surprise, I got a rather strong line.

I know it’s not positive but Glow is saying chance of fertility is only 1% and ovulation is further away. Is it common to ovulate early into your cycle, rather than around CD14?? I’ve always had a predictable 28 day cycle.
