Has this happened to you?

Ok so I've been on bc for almost 2 weeks. When i started bc pill i was starting my fertile window. I know my body and know when i ovulated (4th day on pill) . And today out of no where i felt something down there and thought "crap! Did i just start my period "? So i went to the restroom asap and i wiped myself and I had EWCM Coming out! I know it was that for a fact. So i was like wtf did i just ovulate "again " my period is due within 10-11 days. So has this happened to anyone while on the pill?

And yes , i know the pill is to prevent ovulation lol that is why i found this weird
