Ewcm day after period ended?

A.💕
So my period ended on the 26th on the 27th I still had some spotting but my husband and I bd and on the 28th I noticed a ton of ewcm... This was over 12 hours after bd could this have still been semen? Or could I be having ewcm this soon? This was my first period after delivering my son at 16 weeks prego...
