Okay so not sure how to tell the difference!!!

I've been taking vitamins that supposedly help my body ovulate my app says I'm not suppose to ovulate until the 29th but this app isn't that accurate with my cycles idk why, but last night me and my husband baby Danced And Today when I went to The bathroom I have very thick stretchy CM but not sure if it's EWCM Or left over semen??? Can anyone help on this it's super super stretchy and it's clear when I stretch it out but when it came out all at one on the toilet paper it was kind of like a cloudy glob of mucus
