Positive OPK but no discharge?

Le

okay guys so ive been having positive opks for two cycles.. BD at those times but have not been successful in conceiving .. I have not noticed eggwhite discharge.. question is, do I need to for sure see that cm or can i still have a chance to ovulate without it? 😥😥😥 i take provera 10 mg for ten days to help with ovulating and regulate period..
