Hi. My Boyfriend And I Did Unprotected Sex For Like

Hi. My boyfriend and I did unprotected sex for like 30 seconds. But we made sure he urinated before we did it and I am also done with ovulation (base on my calendar). I took Nordette after 96 hours, just to make sure. I also did it on the right amount. 1st dose and 2nd dose after 12 hours.

But my period is delayed, it's been one week since I took Nordette. Is this because I took it the day before my period is supposed to come? I also feel breast tenderness and increase in white vaginal discharge. I am so worried. Pls answer me.
