EWCM before period?

Libby

I had a positive OPK on 5/19 and the spotted 6-9 dpo and have been waiting for my period to come... we’re seeing a fertility specialist and once I get my period we can start testing but I haven’t gotten it yet. Yesterday and today I’ve been having a lot of EWCM... is that normal? Not sure if I had a false positive OPK or the EWCM is a sign my period is coming soon?
