EWCM?

Hey, my husband and I have 3 lovely healthy daughters 14yr old, 6 yr old and a 13m old.... October 2018 we had a miscarriage at 5-6weeks and then became pregnant in December 2018 I carried until I was 16 weeks and miscarriage what would’ve been our first Boy..... this was March 2019..... I have been keeping track of my ovulation this far and tried but we haven’t conceived as of yet. My OPK says negative but from yesterday to today I have had this type of CM (yesterday’s was a little thicker not by much with a little white but stretchy) is this EWCM? We BD’d yesterday
