A little confused

Jenny

I’m hoping someone can help. AF was supposed to come on the 2nd but never did, not even a trace. I’ve taken several tests but they’ve all been BFN.

Now tonight I noticed ewcm when I wiped and according to the app, my fertile period would have started on Sunday if AF would have come on time. Is it possible to ovulate without AF?

ETA I also had ewcm and positive opk on 1/18
