No egg white Cm

Have anyone else have no EWCM after a leep Procedure I had a leep procedure done 9 years ago and I just started tracking my cm for about 2 years and I noticed I never have any ewcm and I was looking up online why might I not be having EWCM and that was one of the reasons so I'm trying to get pregnant so what do I do since I have no EWCM I've tried preseed and nothing I've tried promise evening oil I've tried fertile cm and nothing is helping with EWCM
