CM after BM then nothing

So I noticed a quite a bit of EWCM right after my BM in the morning and then the rest of the day nothing. I’ve been doing ovulation tests and they’ve been negative so I’m a little confused. If it is ovulation then it would be a little earlier than last month so I’m not sure if it’s true EWCM. I just want to make sure I didn’t miss it this month, hopefully not. I’m going to keep charting, taking the daily and clear blue ovulation tests. I did BD later the same day but the rest of the day I didn’t have the EWCM. Any insight on this would be greatly appreciated.
