ovulation w/o ewcm?

Hi ladies, I had TVS done yesterday and my OB saw I have a dominant follicle in my right ovary (measuring 1.6cm). She said it cud rupture within 3 days. I thought my fertile window has ended (im on CD17 today). So jus want to confirm I can still get prego if my hubby and I do some more bd within the next 2 days. Right? But I checked my CM and it's not ewcm... but I think I will use Conceive Plus to help the swimmers get in there ready to intercept. :) Here's hoping!
