Should I be concerned?!

Serena • Soon to be first time mom. Trying for our little "Caramel Macchiato" Harris. TTC#1
I'm on CD16 and I can't tell for certain if I really gotten my EWCM. I'm taking prenatal vitamins, low dose aspirin (to promote blood flow to the uterus) and mucinex (to loosen up the CM) my opks tested positive for ovulation so we been BD for the past few days. Should I worry that I didn't get the EWCM?
