PRESEED OR EWCM?

Two nights ago I used some Preseed but fell asleep before we could BD. I woke up the next morning, took a shower, and later that night noticed what looks like EWCM. Last night I used Preseed and we did get to BD and this morning again, a lot of EWCM. My question is could it just be the left over Preseed both days or is it actually EWCMO? FF predicting I should be ovulating around today but this is my first cycle tracking.
