Ovulation/Cm

Hello ladies, I need some advice and guidance. So I had my period on the 12th of this month. I started getting ewcm since this past saturday. I know that when you get that type of CM it means your close to ovulating or are ovulating? Now since yesterday morning I have been having cramps in my lower abdomen and my lower back and they will not go away and have been so tired all I want to do is sleep. The cramps are not gas or constipation. Can you ladies please help me and maybe give me some advice what could be going on with me. Below is my calender from glow, with all my days I've had sex on there. Thanks in advance and baby dust to all!!!

Also when I look on tomorrow's day it says 33% chance and today is like 27%.
