Cramps!

Tamara • 20 white female. Ttc #2
So I have a 33 day cycle and just finished AF so not due till 26 ovulation is supposed to be this week says glow and a few other sites like web MD but today and yesterday I have been cramping pretty bad took an ovulation test and there was next to no line at all my CM is pretty clear but thick? So confused on what's going on and why my belly feels so cramped and weird TTC #2 been almost a yr since #1 don't want to get into to personal stuff but needless to say I don't have #1 anymore.
