Positive ovulation test but no EWCM?!...

Crystal
Can I ovulate even without the presence of EWCM? I'm confused. I had it EWCM last  month when my opk said I was ovulating but I didn't get pregnant 😕. Today I got a happy face on my opk but I don't have the EWCM. So I guess I'm asking if I can get pregnant without the presence of it ... Thank you for any input you may have :).
