never gotten EWCM

Reesa🌺
If I've never gotten EWCM before how do I know if I ovulated? OBGYN said OPKs are useless with PCO. If I don't get EWCM does that mean I haven't ovulated? Confused?
Update: thank you all for the responses. It's really hard to get a response unless it's because you found your husband sexting or with another women, lol greatly appreciated. I'm currently in my TTW with my first round of clomid, update is I get my BFP, but still going to wait until my first missed period. Thanks y'all!😘💗🌺💘💝
