Pregnant or paranoid?

Patient: I’m a female, 17. I class myself as a virgin but the head of my boyfriends penis has penetrated me about a week and a half ago (no condom, no pill). He did not ejaculate in me or near my vagina. And I was fertile at the time as I was ovulating. I have been feeling strange, I am getting sticky white vaginal discharge daily for about the past three days and am now getting rib pain, or pain under my ribs. My period is also due in three days on the 14th of December. Am I pregnant or just being paranoid?
