Im irregular so never know when i ovulate but Ive been having EWCM for 6 days now. We DTD last night, & this morning I tried doing the water test to see if it was sperm of EWCM but couldn't really tell what I was looking for so I'm still unsure. Is this EWCM or Sperm?

(Excuse the cotton bud, couldn't get a good enough picture with my fingers) I also took an OPK at the same time & got this. (I know it isn't positive but I think yesterday's was lighter. Didn't take a pic of it because I thought I might have O'd already)
