Clear discharge like what I usually get when I ovulate

I am suppose to get my period today but my body hasn't felt right lately. I've had unprotected sex but I'm on the pill and have not missed a day. The worst I've been is taking it a few minutes before or after the normal time I take it. Now idk what to think my period hasn't started and I've had clear wet discharge. Anyone have any ideas if I could be pregnant?
