Sorry if this is TMI. But is this EWCM?

I don't ovulate regularly (or that I know of) but had an HSG done in July. They say it may help ovulation for women with PCOS. I ovulated last month right after the test- and now I'm not sure if I ovulated again. (Haven't tested yet). Is this EWCM or could it be excess semen? (hubby and I BDed last night- and all week basically just to be sure). I'm on CD 11.

When does EWCM happen in the whole ovulation cycle? Like when should I be ovulating- if I was a normal person.

Thank you all in advanced.
