Received my first shot nov 15th had unprotected sex 10 days later symptoms of ovulation on the very next day. Any chance of pregnancy?

Yes, but low chance. You can get pregnant anytime during your cycle, albeit less of a chance around the time of your menstrual flow. The chance is much higher during time of ovulation--mid cycle for most folks, but it can happen at any time. Ocps, iuds, implants, and injectibles/depo are highly effective, but not 100%. You can check a hpt to see. Consult doc for problems. Good luck.
