EWCM before AF? Or before BFP?

LM • Pregnant with #1 due June 2018 🌱

Does anyone get EWCM right before AF is due? I've never ever noticed it before and had it 2 days in a row yesterday and the day before on CD34 & CD35 but nothing today. Im feeling a dull ache on the bottom part of my tummy as well. Help?
