Five days of EWCM with no LH surge

I have irregular cycles that have recently fluctuated between 29-35 days, with ovulation fluctuating between CD 16-22. I usually have several days (sometimes up to 6) of EWCM leading up to/around ovulation. I am currently on CD 19, I’ve had 5 days of EWCM since CD 15, but I am still getting negative OPKs. I have been testing twice a day (three times so far today because I was convinced I must be seeing a peak soon). This is my first cycle tracking BBT so I will have to see if that adds any valuable info. I’m just curious if anyone else tends to experience so many days of EWCM before ovulation? I know EWCM is a good sign, but is there such a thing as too much/too many days? I’m worried my body is gearing up to ovulate but is not actually going to. Hoping I will get a positive OPK soon, but levels have been staying very much the same each time I test. The waiting involved in this journey is just so tiring.
