4 days late and a lot of clear discharge?

I haven’t had sex recently- or at all for that matter. The clear discharge has a strong smell and it feels like my period is coming but instead it’s just the clear discharge?

I must mention that A few weeks ago my bf and I were playing around and his penis did touch my vagina but did not penetrate. No semen came near my vagina either.

I haven’t been sleeping well lately and have been going through my exams- stress. Could that be the cause of the discharge and late period or am I pregnant??
