Hello! I Just Have A Question, My Boyfriend And I

Hello! I just have a question, my boyfriend and I had intercourse a few weeks ago, and these past couple days i have had nausea, fatigue, and frequent urination. I am considering taking an HCG urine test due to these symptoms, however, when we had intercourse we used female spermicide, a male condom, and the intercourse was right after i finished my menstrual period. Also, we stopped shortly after beginning, so he never even ejaculated. Is there even a possibility of pregnancy? Or is the paranoia and anxiety i have about it causing me these symptoms?
