Had sex on nov 18th with a 30day cycle had a period nov 2nd now can i still get pregnant if i have sex on the 18th of the month?

I would think so: For a menstrual cycle that began on November 2nd, November 18th would be day 16. While typically that would be beyond the fertility window, in a 30 day cycle, you could still be in there. If you are trying to get pregnant, have intercourse earlier in your cycle or use an ovulation predictor. If you are trying to avoid pregnancy, please use more reliable methods.

Yes: Based on your dates, and that you had a period on 11/2, you may likely be ovulating this week. Count 14 days back from the first day of your last menstrual period, and that is approximately when you ovulated back in October. Add 30 days to that date, and you get this week. Hope that helps!

YES!-This month: Last month you are ok, because you had a period after your sexual encounter. This month, you are getting close to the day you would ovulate (2 weeks before your next cycle), so you could certainly get pregnant if you had unprotected sex. If you do not want to get pregnant-Use Birth Control and CONDOMS to prevent STI's also. Best wishes.
