Any time you have unprotected sex, pregnancy is possible. Pregnancy is most likely to occur when sex occurs around the time of ovulation. If you have regular menstrual cycles that last about 28 days each, you are most likely to ovulate (release an egg) on day 14 (with day 1 being the first day of your last period). If this is the case, and you began your period on February 17th, you will most likely ovulate on or near March 2nd. Every woman is unique though.
If you are interested in determining your fertile period, contact a medical provider (OB/GYNs and Family Planning/Planned Parenthood providers will probably have more information than general practitioners). Fertility awareness or natural family planning combines several natural methods (calendar/rhythm, basal body temperature, cervical mucus) that help you determine the days of the month you are most likely to get pregnant.
The only way to know if you are pregnant is to take a pregnancy test. The best time to take a test is one week or more after a missed period.
