Positive OPK, but no EWCM?

Bi

I got a positive OPK yesterday morning at 6am, but my CM is still watery, and when I took another OPK this morning, it was negative. Could I still get pregnant?

To note, I did not test the two days before yesterday morning as I have a nasty cold rn. I didn’t finger test my cm, but discharge didn’t seem like ewcm then either.
