Cm ???

My partner and I had sex on the first three days of my fertile window and he came inside me every time . I'm on a 30 day cycle so sex occurred day 11,12,13 and glow says that was the first three days of fertile window and I had egg white cm those days and cervix was high soft and open but now three days later it's still high but medium and I'm getting this cm . What could it be ? It doesn't look like ovulating cm . Currently on cycle day 16
