Anyone had this happen?

I had EWCM & a positive OPK . When we had sex that night there was white cream on his penis.. idk how it went from ewcm to creamy that fast but i looked it up and people are saying they get that when they’re fertile/ovulating.. anyone experienced this!? just worried it may have messed up my chance of conceiving ( no i don’t have a yeast infection or bv )
