A lot of ewcm and solid smiley

I just had a miscarriage. Haven’t had a period yet. Looks like I’m ovulating today or tomorrow. I got a peak solid smile on Clearblue advanced OPK this morning. This is the most EWCM I’ve ever had before. It came out in a large glob. I was shocked. I’ve had nothing completely dry CM leading up to today. Do you get a lot of ewcm day of or day before ovulation day?
